I just got a Xbox for the first time. I logged in with my existing gamertag which I created some time ago on Games for Windows Live. I know that new owners of Xbox get one month of Gold for free, but I received no prompt or code for it. I've never used Xbox LIVE before, and my gamertag and email has never been associated with Xbox LIVE Silver or Gold. Does anyone know how I can get my one-month trial? Thanks in advance.
