Forum:How do I fix my gamerscore from broken steel??

I saw that the achievement was not working for "Death from Above" and that as of now is working. However, I got the achievement on the 360 before the fix came along, and so I do not know what to do to get it counted on my Gamerscore, Mygamercard.net, and my xbox.com profile. Any help would be awesome if someone knows how to fix it. I am going to try to replay that part of the mission, since I do have a save slightly before it starts and hope that I get it from that. But until then, please any suggestions??
