Re: Mine crashes as well !
I ran the steam support program and realized my video drivers were out of date because I forgot that I had to system restore to fix my sound. But I fixed that and ran it again and everything passed except for this:
* Services: Failed
The following services were found on your system. Please try disabling the service or uninstalling the application assoicated with them, and see if that resolves your issue
o Service: Ati HotKey Poller
Ati HotKey Poller has been reported to cause mouse and keyboard lag.
I did disable the service, but I can't figure out how to uninstall it. After fixing all these problems I can run the game for awhile but still get booted with the same "memory could not be read" etc. error message seemingly at random. Sometimes I get a good 20 minutes of game time, sometimes a lot less and sometimes it crashes right when I load up a game. I also tried each and every tech support suggestion listed on the steam support program, none of which seemed to help. Please help.
