When I tried to play the World of Tanks beta this afternoon my xbox promoted me to re-enter my account info to sign in. After doing so my xbox gave me a message saying "Sorry, something is wrong with your Microsoft account. Go to http://account.live.com for help. Code: 831188FE. I I went to account.live.com for help with the error code. The customer service rep walked me through all these steps to clear my profile and the cache but none of it helped.
