Typed in the exact URL given in the console message I received: XCL.Xbox.com/Beta.
Upon doing so I received this:Server Error in '/' Application.
The resource cannot be found.
Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly.
Requested URL: /Beta.
Now, I contacted support about this issue yesterday and they said that it would be resolved within 2 hours. Try to fix it this time.
Best of luck! :)
