Can't get online with your Xbox 360 after running the latest Xbox 360 dashboard update? You're not alone, though the number of people affected by this unfortunate Xbox LIVE access goof is said to be small.
The issue involves Xbox LIVE user profiles, and prevents users from downloading those profiles from Microsoft's servers, thus locking them out of the service and barring them from accessing purchased content.
Joystiq registered complaints from users impacted by the issue this week and collected at least two error codes, notably "801540B7." Microsoft responded to the blog by email, admitting:
"We have recently identified an Xbox Live profile data error that results in Error Code '801540B7' for a small number of Xbox Live members. The error instructs users to attempt to re-download their Xbox Live profile and directs them to customer service support for further assistance. We apologize for the inconvenience this has caused to our loyal Xbox Live members and are working to resolve the issue as soon as possible."
The issue apparently manifested after Microsoft overhauled the Xbox 360's dashboard and Xbox LIVE services on December 7 (the update was originally due on December 6, but delayed a day). The update included Microsoft's "Metro" tile-based interface and a new Bing-search-powered voice command interface (requires Kinect) designed to drive you from a search term like "Iron Man 2" directly to the end content services (e.g. Netflix, Zune, Vudu) without intermediary navigating.
Again, Microsoft claims the number of people impacted by the issue is small, and it's obviously in the company's interest to get it rectified as soon as possible, though with the holiday weekend looming and employees nationwide on the way out (or already off), I wouldn't bank on the fix coming pre-Christmas.
