The definition of insanity is to do the same thing over and over again and expecting different results... well, seems like i'm insane.
I tried to start the game over and over again, with a glimpse of hope that it magically recovered, and all of sudden it told me it was missing the "cudart32_41_22.dll".
Downloaded that dll and boom: It works. At least to the main menu. Havent tried further.
Edit: Okay, game seems to run like it did before humble bundle. Sorry for bothering you
