That game will not run on 64 bit. It was designed for 32 bit.That will be the problem with the overlapping OS's going on now. Unless you can dual boot with XP or something else I dont think your gonna be able to run it. I had the game since it came out and there is very little support for it, but you may want too check the game's forum. If it even has one. I don;'t know if thy ever even got the multi player mode finished as there was no servers when I had the game. Not much use.
