I had it, and then my laptop had problems starting, and it restored to a date that didnt have it on there. Then I reinstalled it, and had further problems with something, to which I stupidly unistalled it. Now, when I try to run it, the menu pop up, and play singleplayer and play multiplayer just crash it. There is no install wizard that shows up, the unistall button on the menu doesn't help at all, and there are no files on my computer relating to cod4. I'm at a loss here, and I would love to play this game again. Any help at all would be appreciated, thank you for your time.
