I don't think the problem is the PC. I have 233Mhz and 32 Ram and ir runs almost perfect. It crashes sometimes in the program and everytime I exit the program, but the rest is fine. It might be your video card. I heard it has problems with geforce cards. Try to disable opengl and to reduce the wireframe quality. Or download the latest patch. It might work. If you can't make it work try to return it, but I don't think you can because you already opened the package.
