I got this runing my game. Right before it said something about not being able to save some sprite backup file

Edit:

hmm.. everything seems to be working now. Had a small crises with an object but after re-importing the image a few times it seems to be working...

Did you run out of disk space by any chance? If it couldn't save the game files correctly, that could explain why the game wouldn't start up.

Nope I have 25GB...
