So I've recently updated my laptop from Windows 8 tot 8.1 and this caused a problem with CityEngine. Upon starting the program it gave me this screen:
When I opened my administrator it told me that my license had become 'untrusted' which could be a result of the software update. So I ran the repair screen and the administrator told me that my license was once again authorized. However CityEngine still gives the same error message.

I already tried a clean install which turned up to be a dead end. I really need this program to work as I need it for my internship that I'm currently doing.

Is there a fix for this?
