Closer Analysis Glitch!!

[AnnMaryxx]

Hi,

I was wondering if someone else had this problem:
My bf and I are playing on the same console, he allready finished the game (veteran and the closer analysis achievement). When I wanted to start single player, on the first level the veteran achievement black op master and stand down achievement also..

First i thought it was funny, because my bf played a long time before getting the block ops master achiev and I got it right away..

But when I wanted to get the closer analysis achievement, ALL of the intels were gone! So i can't get the achievement anymore.. I tried everything, erased my whole xbox, played on another ones console, or another cd.. but nothing helps :'(

I tryed contacting activision but they can't do anything about it..

Is someone else facing this problem?? Or has someone any solutions what possibly help???

PS: I DIDN'T USE THE CODE ON THE PC
