Well i just got my new xbox sent back to me about a week ago. and today i downloaded the dashboard update fine, then i played a few matches of halo 3 then turned my xbox off. then later once i got home i noticed i couldnt sign in to xbox live for some reason? i tried to sign on a few times. so then i tried to play halo and sign on XBL and it said my account was suspended and i wouldnt be able to sign back on live till 12/6/2007... why? what did i do wrong? is there a way i can even find out?
