Hi there im having a bit of trouble changing my gamertag i'm changing it to the name of a popular halo character as i love halo so much. I have every book CD and game and anything else i can get my hands on that's halo and would love it if my gamertag could be halo'd as well.
It tells me on Xbox.com that the gamertag is not valid and when i look on xbox live to see if it exsists by sending the gamertag a friend request i get a message saying "Can't complete this process please try again" i have done it 5 times now. So i dont know where else to turn thank you for your time.
The gamertag is Noble 6 the spartan you play as in Halo Reach.
