So I signed up for an X-Box Live account via the website. Then I fired up my X Box to sign on, and there's no way to sign on to the account I just set up (and paid for!). Instead, it has me go through the steps to open a new account, and when I put in my email address, it says, "that address is already associated with an account, please use another." WTF? So, now what do I do?
