Hi i just thought id have a quick go on Vietnam in TT, so i was in Ferrari when just starting lap 3 the game just stopped and took me back to xbox home page, strange i thought but as its a digital download i wasnt that worried it happens. So restarted the game and went back to TT in Vietnam in Ferrari and just strting the 3rd lap the exact same thing happened again, any ideas as to why this might happen.  Cheers Davey
