Uninstall the game and re-install it but DON'T apply any cracks!
Then go here:
Code:

and download this Official patch, it removes the copy protection and works as a NoCD as well so you don't need any cracks!
Being 35mb in size it probably fixes some bugs and stuff. I've gone quite away in the game with this patch and not hit any problems, especially the cable car level that's reported to pop up a message if running a cracked game and I'm long past that level!
