I have a 2 CD game, an ISO and MDF. I ran it through Daemon tools last night and installed it. I went to run the game and got the NO CD error. I tried patches, they didn't work. Then i deleted the game from programme files to try and run it again off a burnt disc. Now when i try to use both that and Daemon tools, the options to "play" and "install" are blanked out, only "uninstall" and readme. When i click uninstall the box just dissappears and it does nothing.
Run a registry cleaner and manually search for and delete any traces of the game. That should clear it from your system. However, the combination of ISO and MDF files seems a little strange to me and as the game didn't even work with a NoCD patch, I think it is safe to say you have grabbed yourself a very poor torrent.
