Close Quarters did not download properly

Please ensure that after you manually downloaded the Close Quarters expansion that you opened your server browser filter and checked the new maps and game modes for the Close Quarters expansion or you won't find any games on the Close Quarters expansion.

I did that, however I still see no new maps. I have tried playing with my friends who have the close quarters expansion pack, but once it switches to a new map I instantly get kicked out of the game.
