If you receive; "DirectDraw Init failed: SetCooperativeLevel: after Set Cooperative Level" or notice the game not functioning properly, you may have tried to open a game when there is already a game running. Make sure that you exit the game when you are finished playing and that you don't leave the game running in the background.
This error code can also come up if you double-click on the game buttons on the main screen.
Make sure that you single-click only on the game icons.
