Sound Mod - Problem

I have a problem. I try to modify "GUNS_SND_AR.REZ" because i want to change sound of FAMAS. I would like to use sounds from this mod: http://www.mpgh.net/forum/210-combat...kin-sound.html

But there are only files in *.wav

so i download: rezinject, rezxtract, winrez LT Studio ,

At first I Xtract a GUNS_SND_AR. then i go to this file and choose FAMAS. I change: FIRE, RELOAD 1,2,3 to my new from link.then i open winrez LT Studio to pack this new file with changed famas and the other weapons to *.rez. i sav that as GUNS_SND_AR in Combat arms/game. REzinject makes backup of GUNS_SND_AR so i delete my old file and changed the name of my new file. If i think that's all i open combat arms but then i'm playing i don't hear anything ( only AR) - reload , shooting etc. other guns like smg are working correct.


Can you write which programmes i need to do that? i don't try to change FIRE file ( for example Famas with sound M416 CQB) but i will try it. Maybe a problem is that i can't change FIRE file from download on nexon file. i use DTX Convert but this isn't *.DTX so it doesn;t work. Or you can write me how do you do that. maybe i will find a mistake. Pease for help.
