i just connected my xbox to my router, and the connection is fine and all. but once i made an xbox live profile, it just changed my gamertag to some random name: HeartsickSun6 and left me there. when i login on my pc i get the same gamertag, but not my avatar correct gamerscore etc. when i try to sign in on my account on the xbox i get this weird error stating: this email address or password isn't valid for this account. Try again. im sure the email and password match up. anyone got some ideas?
