Resolved my game crashes on startup

my game crashes on startup, my pic turns green and then it goes back to blue 5 secs later. I'm using a 970m and drivers are up to date. halp
this is the only game on steam that this happens on, so its definitly something about this game that my drivers dont like

EDIT: in the error logs it says:

Message: Error loading "LooseSprites\daybg".
