Hello 757, Whats the error you are getting actually. There can be a range of reasons as to why FS is not loading. First uninstall everything off, once that's done, go into the directories where you have installed FS and make sure those directories are deleted off and also make sure that in your documents and settings, My Documents folders there are some folders of FS, remove off all these traces. Infact you could check the registry too if there is something of FS which you could remove, but before that backup the registry.
Restart your system and install the fresh copy. Preferably restart again, but this is not required. Start your FS2002.exe file, wait for a while and if nothing happens, check the task manager to see if the process has started.
I think this should help you start up the game, I dont think there is anything else that can be done. You could try one more thing, do you have other games which uses graphics to the core like FPS (First Player shooter) games etc. Try if those are running, that should help you figure out whether FS is giving the problem or something wrong with the system end. Try installing DirectX again too.
Hope this helps you 757. I had faced a near similar situation but not with FS with some other Racing Game.
