Cant play on playlists

Hey I just downloaded the two map packs needed to play the extra play lists in matchmaking like Rumble Pit, Social Skirmish, Squad Battle, etc. and it says that I dont have the maps required to play in the said playlist. I dowloaded the Mythic map pack and the legendary map pack. am i missing something or do i have to update something?

Did you miss the Heroic Map Pack and Cold Storage? That could explain why.

nope i dowloaded them a lonnnnnnnggg time ago like back in 2009 lol.

Alright, you do know that the Mythic map pack has two parts?

Mythic Map Pack I, and II.

ok that would be my problemm…thanks
