Game not saving on PC (Steam)

[Guest]

Yeah when I first bought the game I kept getting an error and the game wouldn't start. Had to change the security settings on my documents to get it to work at all. This is the only game I've ever had to do that for. After doing that, however, it worked just fine. It's only today that it stopped saving. Ive also been running the game as an administrator today, no luck.
