I bought my license last year around this time and I used Usine2. Now I have upgraded to Usine3 and at first things worked fine. But now it says that my license has expired every time i open it. I have tried to activate it with my activation code, but it doesn't work.
Does anyone know why, and what I can do about it?

Thank you in advance for answers!
