I know you said DX3 was installed before but stranger things have happened. Anyway, DX5 will be on the game cd. Unfortunetly, you can't "downgrade" DX so removal of version 7 would required first. Play with the resolution first and see if you can get it going. Here are a couple of MS articles concerning that game and error message.
Good Luck!
