How do I fix Tom Clancy's H.a.w.x, not giving me gamer points for campaign completion?

I've been playing H.a.w.x online co-op and I was getting achievement points for beating the campaign with a friend, and had to get off for the night, the next night I got on and we were beating the rest of the campaign and I noticed I wasn't getting achievement points anymore.


Anyone know how to fix this without deleting the game from my hard drive?How do I fix Tom Clancy's H.a.w.x, not giving me gamer points for campaign completion?
Probably, it's registering as that you didn't fully complete it on your own or with your friend. Don't worry, just do it again on your own or with your friend again and you should be fine.
