I recently Torrented Bioshock, and i installed it successfully and other problems ect, to the point i can actually start playing it. But whenever i open it, nothing loads up and if i open task manager, i open Bioshock again, i see Game.exe on process list for a few seconds then it would dissapear like it was delelted from there and so it wouldn't start
