About a month ago I downloaded the black ops map pack acension i think, the one with the map hotel. I had 2 black ops games at the time, both working, one for my brother and one for me. So i downloaded the mappack and started playing. I reached a map called Hotel, and it loaded, but once the loading bar filled up the loading circle would just keep spinning. And spinning. So I kept on trying and nothing, all my other maps worked including the first strike mappack, then i went to play kino and some five. I then called Xboxlive support the next day and told them about the troubles iv been having, so they told me to clear system cache ect. It didnt work, so i just went and forgot about and played some kino and five. I loaded up five and it didnt work. The loading bar filled up and then my xbox froze, same thing for five. I've tried 2 other xboxs and 2 different disks and i still get the same thing. please help! I'm very angry that i cant even play the game mode that made me buy the game!
