I recently got an XBox and have set it up with a profile for me and have used it for a month. I decided it was time to connect to XBox Live where I've had a Live account for many years. I finally figured out how to do so from the XBox but it created a new profile with a different name (the name I setup from the account on my PC). That's not what I want. How do I assign my online account to my existing XBox profile? Thanks.
