Hi rhiann,
here’s a fix that might be able to help you: Activation Issue Again - #89 by narrsd
It’s a bit involved, but lots of reasons in that which make it able to work.
As you’ll see in the note, I got this from Scrivener support, and after this, no more troubles – while I have the fix ready should they recur.
If this is too daunting, or not a fix, you should get hold of Scrivener Support where they can talk to you, which is not online for llcense matters.
You’ll find them very kind, friendly, and accurately helpful, and they’ll do this by email.
Here’s the link: Contact Us | Literature and Latte
It’s not Scrivener that’s at fault here, it’s the licensing service, and there are not too many alternatives of those which are suitable for a small business.
Best on this, of course
Clive
