I'm trying to add a .wav file to my mod which needs to be played everytime i hit somebody with my modded sword. The problem is that if I go to the 'music track' menu and add a new one and select 'single track', when I select my .wav file i get 'Invalid directory'. I've tried placing the file everywhere, \Steam\steamapps\common\skyrim\Data, \Steam\steamapps\common\skyrim\Data\Sounds, the Skyrim folder in My Documents, the Skyrim's root folder, a custom folder inside Skyrim's Data folder ... nothing worked, still getting the 'Invalid Directory' error.

 

Hope that someone can help me, this is quite frustrating :(

 

Thanks!
