No Free-For-All after downloading new maps?

[barry pound]

Hi all, I've only been playing MW3 for about six months and decided to buy some new maps. The ones I have include Oasis, but now I have downloaded them and installed them I can't access Free-For-All, either Hardcore or normal. It says 'no games' when I try to join a match, anyone have a clue why this happens?

Me too!! I buy a Final assault DLC and suddenly i can´t connect to Domination (most played by me) and others mods in Normal or hardcore. Except Team deathmatch, but most times those are new maps, no standard maps.

PS: sorry for my bad english
