I have beaten the game, and haven't got a single achievement yet. no mission completes, game finished, ace 1, ace 5, or either collection achievement. Has anyone else had this problem or know what the problem is?

hello??

I just finished the game on Xbox 360 and had the same problem. I legitimately beat everything except for getting the last ace medal on Berlin 1945 (I used God Mode for the couple of minutes where you have to survive until the rest of your squadron arrives so I could actually shoot down a few planes during those 2 minutes instead of just flying around not dying) and no achievements. I have tried clearing the 360's cache a few times, moving the save file to a memory and nothing seems to be working.
