I played this game on my PC for over 25 hours.....nvever had a problem. I have one of the best graphic cards out there and a decent computer running Windows 7 - 64 bit with 4MG ram. One day, it just stopped working...won't launch. I've tried launch it from Steam and it wants to start but brings me back out. I've tried launching it directly from the D drive, where the DVD drve is, and the same thing happens.
