I just upgraded my xbox live gold account to an xbox live gold family account. In the process of adding my son to our xbox gold family, it never gave me the option of adding an already existing gamertag. It just assigned him a new gamertag and windows live ID. My son has had an xbox live membership for about a year. It just expired. Instead of renewing his gold account membership, I upgraded mine to the family account. Is there a way for me to add my son's original gamertag to our new family account? Any help would be appreciated. Thanks.
