I finally uninstalled today, I have the steam version, maybe thats the only version for all I know...anyway, I wanted to like this game, but the negative mouse accceleration is unforgiveable. I just upgraded my motherboard and processor to a i5 from a core 2 e8400...a modest upgrade...this game is just broken....can't blame my rig or anything else. Maybe they'll patch after 5 years or something.
