Working on a friends computer, new Compaq 520, it had Vista on it and I changed it to XP Pro. Had problems with Active X and DirectX but resolved that with 9.0. Now I have a problem, My friend is trying to run a 3D train Program and it will not play nor completely load...it flashes that it does not have direct 3D...Where Do I get Direct 3D and how do I install it? Any Assistance would be appreciated. Thanks 1tradnwilli
