This happens to me too, but only on my PC and not my Mac - not comfortable with trying the fix in this thread - it will take me forever and scared of losing all my drafts. Can someone from Scrivener tell us when this problem is planned to be fixed please? 
Iām getting this error message as well. date 12 Sept. 2019 (Happy Patriotās Day!) and it kinda spooked me. I hope that you guys provide a fix or a patch or something to make it go away.
Cheers!

An update to fix this is imminent.
Your data is stored separately from the Scrivener application, and should be right where you left it, even if you have to completely deinstall and reinstall Scrivener. With that said, an extra backup is never a bad idea.

Received this same message a couple weeks ago for a day or two and then it stopped. I received it again this morning, however. No firewall and Iām working online, so thatās not the problem. Could it stem from an incompatibility with Windows 10ās updates to the .NET Framework?
Registered to report Iām having this same issue, same error message as reported elsewhere.
Windows 8.
Iāve sent a support ticket, will follow this thread.
Iāve been having this issue too since Monday or Tuesday, I donāt remember having to put in my activation code during the pop up twoish months ago with the licensing announcement. I sent a ticket on the site but havenāt heard anything yet to fix it.
Today (sep.13th), two weeks after i initially reported this error and started up this thread.
I am still getting this error. and the program takes over 20sec to start up
Please inform as soon as possible what actions i should take to resolve the issue?
do you think that a support ticket would do the trick?
i have no conflicts with antivirus or firewall programs (set to allow all to scv.)
window defender is disabled
TLS 1.2 is installed on the machine (windows 10. build 193)
please help, it is not very comforting to know that i save my [important] work with a software that behaves weird
After having received the warning notice every day for about a week, yesterday and today Scrivener has opened without a blip.
I am also experiencing this error recently (āYour automatic re-activation with our license provider has failed for more than 2 monthsā). Just got it again on the morning of 9-13.
Same message for me this afternoon. I look into the forums for the first time in years and find that practically all Windows users have the same issue, which for a couple of weeks, yāall were perfectly happy to blame on EVERYONEāS firewall settings, internet connections, or whatever. Apparently never occurred to you that YOU deciding to go with this half-aed new billing company is the problem. You want Paddle to handle your junk? Then YOU frieakinā fix it. I love Scrivener, but truth be told, after waiting for over a year to get Version 3, deciding to be patient with V2 because Iām generally happy with it, to have YOU (through YOUR incompetent billing company) updating my licensing about 4 times trying to get it to work then telling me that my forever license is about to be stcanned because YOU think my perfectly fine internet connection has apparently screwed up every Windows user on earth ā well, buddy, you aināt the only game in town. Weāll see how you do, but after YEARS, Iām on the verge of packing my bag and leaving.
We are in the process of āfixing it.ā Thank you for your patience. ā Katherine
Just a little hostile arenāt we?
Youāve looked at the forum, so presumably youāve seen L&L have apologised and advised multiple times they are working on a fix, including posts a little before your pleasant and most helpful post.
Iām sure your most constructive post will spur the team to get it resolved just a little sooner.
Am I taking the pā¦? You betcha!
Just signed up for the forum to report the same thing. I havenāt used Scrivener for a week, then today it throws up this error every time itās opened.
Windows 10, latest version of Scrivener.
Same here, signed up to this forum just to report the same error. I have tried replacing the exe file with the fix linked in the other thread, however it now says āDeactivate Scrivener (searching for license server)ā, the same message others have experienced. Windows 10 Home Version 1903 Build 18362.356, .NET 4.8.3752.0 here.
I updated to the latest .NET so it got rid of the lengthy error message. That can be found on the microsoft.com website.
I still get the error message about the license deactivation which is the Paddle issue. Since others have asked about the Windows version weāre on, Iām posting here to say Iām on Windows 10.
Literature and Latte, what I donāt quite understand:
Why didnāt you send us Windows users a simple email with the info that youāve discovered that something is wrong with the licensing system? āHere is the error that a lot of users are getting, if you havenāt got it yet, you should expect it at some point. But donāt panic, yada yada, thereās enough time, just click on the window, etc.ā
Or even just a blog post about it?
And no, I donāt think a forum is adequate for this kind of thing. Thereās info scattered all over the place about it. And itās too serious:
From another post: āIām afraid I will lose all my work!ā
You should really think about your communication strategy.
Hi, I am having the same issues, and have tried the solutions mentioned in this Forum. My worries are the same as many others - of losing hours and hours of valuable, irreplaceable work. Mind you, I could have 100 backups and still worry about losing all my work.
When can we expect a fix to this problem please? And where should we look for updates on this issue?
Iām a windows 10 user and Iāve had both issues starting today. The reactivation message and the activation server failure. Please could you email the windows community with a solution once youāve got a fix - that would save checking this forum everyday which is a time drain when honestly Iād rather be writing. Best of luck with the fix - love Scrivener and understand hiccups happen. 
THANK YOU!
This is my exact feeling on this. The only solution I have found in the forums a. the download file isnāt working for me - just throws another error. and b. the additional instructions are vague and assume we have a certain technical knowledge for troubleshooting. I am a writer, not a software engineer, itās not in my wheelhouse, nor should it be my responsibility to figure out a hack/workaround the software issues- thatās the productās responsibility.
And yes the fact that yāall are not remotely communicating the issue, and even completely ignoring support tickets/emails is literally the worst possible way to be handling this :\
The only response I have gotten so far is a non-support person, so just a random commenter, who made a condescending, unproductive comment about āhave I even read the forumsā. 
ug.
Weāre getting an error threatening to lose all of our work - everyone here has a right to at least some sort of communication in that kind of circumstance.
