That said, a gtx460 is quite a bit different than a 9900gtx, so I would argue you don't meet minimum specs. It's possible the game is trying to do something your game can't handle.
Be certain you have direct x9.0c.
If you can get to any settings get then as low and off as possible.
But definitely contact support.
I've had zero issues with the 50+ steam purchases. Sure would be helpful if there was any friggin clue as to why it decided to crash.
