everytime i play...this error message pops up and sends me back to desktop. sometimes 1 minute, sometime 10 or 20. very frustrating. i am running windows 7 64bit....Intel Core i7 at 2.80ghz, 6gb RAM, onboard audio. i have tried EVERYTHING....set processor affinity, change compatibility setting, changed joysticks, updated driver, uninstalled mods, run as administrator, disable uac, disable nvidia settings, disable firewall, disable virus scanner......etc etc etc........any suggestions?

Annoying problem, not sure what causes it.
Sometimes problems with old games can be solved by installing it in another directory than %\Program Files%.
