I went on Xbox Live today to download the add-on for Bioshock and it sticks at 1%. I tried downloading several demos and they all stick at 1%. I downloaded a movie preview and it downloaded fine. My network settings all check out.
Also, I put in Bioshock and it said there was an update available, but it stuck at 1%. I tried powering down the system, but it didn't do any good. Has this happened to anyone else?
