I cannot help you unless you provide greater detail of your problem.
IE.
-How far into the map does it crash your game? Near the end of the map? In the middle? Near the start? Or right after it starts?
-Are there any Sprites in your map that are known to cause crashes? (IE. they have "crashes SC when viewed" in their name)
Upload your map in your reply so I can take a look at it and see whats going on with it.
