Halo Reach Service Record Not Updated

So after I changed my gamertag in Xbox Live, Today I was checking my service records and i found that my service record in Halo Reach is "This player hasn’t played this game yet"
I played halo reach and i complete it and i played online and custom games and I still got my cd and sometimes i play Halo Reach
So is there any solution ?
I changed my GT for like month ago

Try playing a few more games and give it another few days.

Keep us updated on if it doesn’t update after 48 hours.
