Hey, Thanks for making this awesome mod! I get an error when I want to fire the new guns (Ithica 37 (sic), M16, PPK, etc). There's no sound at all when I shoot, and I get a pop-up message saying "failed to load /media/sound/12Gshotgunfire.ogg - not found". The reload sounds work all right, though. I followed the installation instructions to the letter. What's wrong?
