NitePr Code Problem

Hi i Recently added some codes to my nitepr for Starwars battle front renegade squadron and i Was all Happy that the codes where gonna work but they didnt..... well most of them did But im having problems with one type of code ... The Code is Rapid fire and unlimited ammo ... WHY DOESNT IT WORK i know that it has nothing to do with the code becouse i tried many diffrent codes... everytime i put rapidfire it doesnt do anything.. Is ther something that i am doing wrong.?:sad: do i have to do something to get it to work? i have tried going to the PRX option and Puting Cheat Hz to 15/1000 but that doesnt work Please help me i really need this code to work
