Help: MW4 IS Mech Packs

[ExoTerra]

I got the razor release of the mw4 is mech packs, I bought the originaly mw4 so no problem there. I install the packs and everything goes fine, but when i go into the game there not there. If anyone else has this problem or knows a way I can fix this a reply would be greatly appreciated. I am also looking for the MW4 black knight cracked PR 1 patch and the MW4 cracked v 3.0 patch.
