Activiation/Unknown Serial number errors when trying to register (WIN10)

Hi,

Purchased Scrivener from L&L/downloaded/entered key/got prompt to register/hit register button

Still getting the registration prompt when launching the program
Get unknown serial number error as well
Tried the offline activation and got an error a while after hitting “submit” button

Any help is appreciated.

EDIT:
Tried rebooting, still didn’t fix.

Got registration to work.
2 things I did differently, so not sure which one was the reason it worked:

1.) Launched Scrivener as Administrator

2.) Was not aware you could try to reenter the serial number via the help menu - I did this

Scrivener activation and registration success :smiley:
