Add-ons not working!!!

None of my bought add ons are working!

2 days ago I bought the warhawk bundle,installed but nutting showed up,no maps and I couldnt join any game with the new maps(red dot on the left of the servers host)

today I bought the solo addon for super stardust hd and it also wouldnt show up!!!

can someone please help me?any help would be realy appreciated!thx in advance(if you post anything :P )

maybe because the game is from a different region.

because it might only connect to a foriegn server

I bought a ps3 and iv tried to get the new map pack for cod4 and some track packs for guitar hero 3, they download and they install but then wen i come to try and play any of em its like they've just dissapeared from the system :? is there anythin i can do or am i stuck with it?
