I backed up Sudden Strike but now It wont play
 

Ok I backuped the game, but now it will not play. How do I use the GameCopyWorld Patches to make it run. I used the 1.1 patch crack and the game ran for about 5 seconds and crashed. I cannot install the official 2.1 patch because it says no instance of Sudden Strike was found; likewise, the official 1.1 patch is no longer on the Sudden Strike website. Please explain and be specific.
