So I'm having live stat problems For Halo 2

So I played Halo 2 On Xbox while it was still available. But I changed my GamerTag a few weeks ago, but my Halo 2 Stats never came back on this site. They Do However appear on Bungie.net : http://www.bungie.net/stats/playerstatshalo2.aspx?player=BeguiledTurnip
So I’m wondering if there is a way to fix it. Plus I have gameplay to prove it : http://www.youtube.com/watch?v=QsZf48jV5mM&list=UU1wLPxRRf7MPzIVuhJfIjwA&index=10&feature=plcp
any solutions?
