It started out as not being able to accept, decline, or delete friends. So i turned off my xbox, unplugged the router, the whole sha-bang. Now i can't even sign in to xbox live and i get a service alert yellow caution sign when i connect to xbox live in the diagnostic. Then i tried reloading my account but when i tried that i got the error code 80004005 so i restarted my xbox etc. etc. Now my account isn't even on the list of sign-ins for my xbox. THIS JUST KEEPS GETTING WORSE AND WORSE i'm not asking for an immediate fix, take your time. But at least let me know that you understand my problem and you're in the process of fixing it.
