This has only been happening to me the past few days, but I've left it alone just thinking it was something wrong with Marketplace at that particular time and it'd "fix itself" eventually. Well, that's hasn't worked. FYI, I was in the Beta that just ended last week and never had the freezing issues happen to me during that time. I did read that some users were having that problem during the Beta, but again, I did not. It's only happening now.
I'm trying to download the three Assassins Creed III "Tyranny" DLC packs that's part of the "Back To School" promo. I can access the first chapter and am able to purchase/download it, but when I access the second or third chapter to purchase/download, my console completely freezes, just after I press A that takes me to the "purchase screen". I've tried again a few times, hoping that it was just a one time error, but each time I try to purchase/download those two pieces of DLC, my console freezes up once again. The only way to shut off my console, is to press the power button on the console itself.
I hope I can get someone to look into this problem ASAP and try to find a potential fix. Please know that all help and replies are greatly appreciated. Thanks.
