Mafia Wont Work

I downloaded Mafia (.bin and .iso) from kazaa and installed it but when I play and try to start a new game after the intro movie while loading it automaticly shuts down. I have win XP, Nvidia GeForce4 MX 440 Graphics card, 80 gb memory, 256 mg ram and 2.4 ghz speed.

Did it have a crack to apply or something?

Yes I had to copy and paste from the cd the icon that starts the game and the icon was in the folder called crack.
