You need to confirm the games actually do work with the original discs first! The cracks (depending on which ones you are using) shouldnt be the problem but you need to try the games without the cracks first. It may have something to do with the cracks tho? I would install only MOH Allied Assault first, then try the game. If it works then install Spearhead, then if both games work then install breakthrough, all without cracks! Then if they all work then apply the cracks. But do one game at a time. Also configue all the games with the minimum setup first, and make sure you do a full install.
