Dragon Age 2 DLC For Xbox 360?

I recently bought the game and downloaded some armor on Xbox Live, the problem is it's not showing up in the game. HOWEVER when I download the Black Emporium it does...Do I need to install the other downloads? If not, why is it not showing up as downloaded in the game?|||check your receipt if you got it from gamestop you go online and register your dragon age 2 and you will unlock aton of items also i am unsure what is wrong with your armor code i put mine in and i got my armor no problem you may have to link your bioware account
