Got the game from Steam and it plays for a few minutes, then it just suddenly crashes and I have ti delete/alt to close it down. Then when I start it again, it will tell me my gameplay has been deleted because of some fatal error. I've googled it and found that other people have had the same problem but no solution. I am playing it on Windows 7. Any suggestions?

Did you contact Steam for help? They are slow, but will hopefully give you some assistance. The forums at Steam for the games are helpful too.

Yes, I've contacted them but haven't heard anything yet. I'm gonna try uninstalling and installing once again. Thanks
