Source-1-Games Left 4 Dead 2 Not Giving Achievements

I have spent a good 7 hours playing this game with my friends. The first time we played we all received achievements for the game. However this time when we played a few levels my friends unlocked the achievements but I did not. We did the same exact things and I know that I reached the necessary requirements for several achievements and it is still showing that I did not unlock them.

OP, please be more specific about which achievements you were not able to unlock. There are also some similar issues:

Still an issue, specifically for "Killing Spree".
