MW3 DLC2 Map Pack Querry

Hi,

I just bought DLC2 map pack of COD MW3. In total 6-7 files were downloaded and I installed them individually from the PS3 main menu.

When I start MW3 multiplayer, it doesnt show the new maps in the multiplayer or the offline split screen menu. I can't seem to find the faceoff maps either.

Can you tell me what I am doing wrong here? Downloading and installing new maps in Black Ops wasnt difficult.

Please note I havent downloaded the DLC1 map pack. I am not sure if I am required to buy that first before I go on and buy DLC2 map pack.

Thank you,
