It's no longer pink, but now I can't start a new game or load an existing one. It's stuck on the loading screen for minutes without anything happening. I attached links to the required files.

If needed, here are my system specs:
AMD A8-6600K
Win 7 64
8 Gigs Ram
Geforce GTX 650ti, latest drivers clean install.
Last edit: Seems like steam did a terrible mashup with my game's data. I reinstalled it, repaired it and repaired it again. Second repair finally did the trick and it seems like I'm able to play again.
Thanks for your support.
