About a year ago I purchased Midnight Club LA on Games on Demand. Since then i have not been able to download it because every time the download reaches 30% it stays there for a while and then just stops. A message pops up and saying "Can't download this item". I have tried deleting the cache and the unfinished file and attempted to download it again, but the same problem persists. I have lots of memory for it, so that is not the problem. Is there any way I can fix this?
