Hello, I am running Batman Arkham City on the xbox 360 Slim with a 250GB hard drive. I have not played the game in awhile 3 or 4 months, and was going to get the new Harly Quinn DLC, put it in yesterday and it immediately wanted to do a game update. Since then when it starts the game it just goes to a black screen and stays there, it never gets into the game. Only way to get control back is turning off the xbox. Any body else having this problem.
