After successfully installing thief 2 metal ages I then altered the audio it then crashed. I've tried uninstalling it but it won't so I tried manually deleting the file folder then I reinstalled it. but the problem did not change it still won't start. HELP
There's a free program called revo uninstaller. Try reinstalling your game, then uninstall using revo, and remove all the registry entries and what not associated with said game, then try to reinstall and see if it can reset it back to original settings and get you running.
