Skulltag sound problem

[splatterhouse]

Alright, so I downloaded a psx sounds wad and placed it in my skulltag skins folder so I could play with them, and now that I deleted the wad from the skins folder, the psx sounds still play. I even tried placing a different sound effects wad in the skins folder, and it won't even load. I tried uninstalling skulltag several times, and I checked all the sound effects in all the wads I've been using with slumpED, and the original sounds are present within them. This shouldn't be happening! Any help would be greatly appreciated! Thanks
