Xbox live gamertag help? Email address already used?

I just connected to Xbox live for the first time. I must have created a gamertag on the internet several years ago with my hotmail address, so now when I try to sign up to xbox live on my console, it just wants to use that really old gamertag and not my own xbox profile. How can I change it so my email address is associated with my real xbox profile and not the old on i made ages ago?Xbox live gamertag help? Email address already used?I dont think you can.
