Hey guys, so i made up my own sixthsense icon and its working fine, acquired an mp3 file for the sound, put it in the *WoTDirectory*\res\audioww folder, changed settings to user sound and yet its still the metal gear solid sound from aslains mod pack, also there was no sixthsense in the afore mentioned directory until i put my mp3 file in there. any clues as to what im doing wrong? Thanks in advance.
