Ive created a profile on XBOX live on the computer and redeemed my code but when I try to add the details onto the XBOX it tells me that the email address is already attached to a GAMERTAG, which I have just set up on my computer - any advice? My gamertag is on the XBOX but I cant add all my details that I have have entered onto the computer. Does that make sense? As you can see I am not very good with technology!!!
