In my Run.bat I think, I just restored my computer to the 5th of June, when it was normal this problem never occured, just after I restored I got this problem.

I am using PI and I can tell the difference between a .cfg problem and a problem like this..

It says "Gui will exit", but my GUI is working perfectly fine.
