ZfreakX: Sorry to bump this thread, but I have the same problem. After a successful install (integrity check and whatnot) FlatOut is installed, but I can't even get to the configuration screen. Starting the game in any way doesn't do a thing. It just crashes instantaneously without any error or message.
And FYI, OS is Windows XP SP3.
Is there any chance I might get this to work? Tried everything I could think of.
Thanks

Zfreak
