Hi fredo thx for the quick answer!

I didn't release anything, but i had a major Windows 10 update, that messed many tiny things! Do you think this could be linked?

Hi,

Ive bought a permanent License, downloaded it and then validate it. Worked fine for 2 weeks, but now sketchup just tell me that my licence expired

I can drop my files from AppData\Local\SCF Licenses if needed.
Thanks for support!
