Boosting not working???

[Boostme]

I go to the lobby (Pro Room, ranked) and me and a buddy exchanged 5 wins in a row..and we still dotn get the achievement..then we do the 10 wins achievment and still dont get it.. Please tell me step by step how to do this. This is very frustrating.

you need to play the last game for the achievements to hit. So if you are going for the 50 win one.. quit after kickoff on the first 49, then actually "play" the last game, and at the end they should all unlock.
