as the title says i go to play far cry 3 and the whole xbox just freezes on the first
loading screen. I downloaded it from xbox360iso and it just doesnt seem to be working.

first i tried installing from usb onto 360 but each time a new file seemed to freeze installation and 'fail'. tried three times and two worked and another didnt and visa versa. i then tried playing straight from usb and just froze first loading screen as i said

if anyone can give me any advice or suggest what i can do would be greatful. i have an rgh jasper on dash 013599.

thanks in advance
