I'll tell you what I did. If you need a video afterwards I'll try and make one. All I did was go into the V3 zip pack, find the .wav files called GraveDiggerLow, GraveDiggerMed, GraveDiggerHigh, and GraveDiggerIdle, and delete them from the pack first. If you don't delete them it won't work. Then find the LongTubeLow, Med, and High, and rename them to the files you deleted, GraveDiggerLow, etc. That's how I did it and it worked just fine. But I would recommend copying the original files to separate folder in case you don't like how the LongTube.wav's sound, so that way you can just delete the files again and drop the originals back in. Hope this helps. Let me know.
