Custom Sound Help

How do you add custom sounds ( such as the ones from Krupp's All in One) ? I seem to have a problem, there is no sound for Rifle firing, well, so far the Looking Glass Rifle and Elephant Gun are making no sound when they fire, the only sounds is when you hit your target (same sounds as if you were using a melee weapon). The readme didnt explain this to me. So could some one post a more detailed walk through?
Ok, I think the problem has something to do with the "aditions" to these weapons. As the Clarington has this same problem. I was able to add the custom sounds for the regular rifles/high tech and the regular pistols. Any help would be really appreciated.
BLAST!
HAHA! JOLLY GOOD SHOW! Somehow, after moving files repeatedly and alot of cursing they WORK!
Thanks for nothing... :: evil smile :: ^_^
