i bought Burnout 3: Takedown and Black the other day off Live. Spent $30.00. After downloading both games, msg. says, "can't start game, try downloading it again". we did, 3 more times each, still nothing. Support says they find nothing wrong on their end. well, my internet connection is fine, and my 360 console is only 2wks old, and my 250GB HD, from Microsoft, is only 5 days old. everything else we download to the mem. or hd works just fine. Is this a problem for anyone sele?
