Hi topogigi,
Is your pc running win XP? If so then there is an option to run progams in compatibility mode, right click the desktop icon for the game - choose properties then choose the compatibilty tab and select win 98.
Problem with win XP is that not all programmes made before 2002 esp. games work with it. You may need to google for patches to make the game run under XP, try looking on the Westwood software site first ( I think Westwood published C&C, but correct me if I'm wrong ) Good luck with your game.
