hmm a idk download something clear the registry and ram

or might be a corrupted game i had this same problem along with few others might have to delete your saved game

Are you running the game as an admin?

Also, as Tzr2 stated, try moving/deleting your gamesave. If you've saved on duty, then this will happen.

Just a quick heads up, the game probably won't run all that well due to your graphics card. Good luck fixing this problem, though.

i've buyed it with steam

I have moved this to the GTA IV Support section where it belongs.
