I bought battlefield Vietnam the same day I bought unreal. I hate swapping the cd's so I dled the NO CD from game copy world. I own both of the games so i thought it wouldn?t be a problem. Well i didn?t realize it would make a potential problem with PUNKBUSTER. Also now I can?t uninstall or reinstall the game at all. Under add remove programs it comes up as Battlefield Vietnam but it says it s 0k in size. I don?t know what this "NO CD PATCH DID" now all I want to do is undo it. If you know how this program works please tell me or if you know what i can do to get the game working normally again i would appreciate it.
