Hi, i already have replaced weapons soungs from ut2004 to UT3, but the game still plaing UT3 sounds, WHY? plz help what else should i do.

?:\Unreal Tournament 3\UTGame\CookedPC\Sounds\
in this directory, there r files like: A_Weapon_Enforcer...
& i made changes on them.

I cut all weapon sounds from this place & weapon sounds still in the game, so it's in other place, anybody know where ??
