Please Help, My Cheat Codes Won't Work!!!!

[ripbps]

I want to use cheat codes in this game, but everytime i enter:
"giveitem zb26", or any other weapon it never shows up. Ammo and health work just fine. I type in the weapon cheat and it recognizes the cheat code but i never get the gun. What can i do?

I think you just don?t have simply room enough for the weapon and ammo, and\or you are carrying too much stuff, like ammo, medipacks etc.
