So I had this problem the first time I tried to sign up for Xbox live, so I came here and signed up. The screen just constantly says something like "This email address is already a windows live ID." then asks me if I would like to use it. So I hit OK, and it led me all the way to the beginning of the signup process, and I changed nothing. It did the same thing. I went back and put in an email address which isn't a windows live ID. "This email address is already a windows live ID." So now I realized that I can't have any of the achievements and progress in my games on this account, only on the offline one. So how do I actually sign up on the Xbox 360 itself?
