I have a grip sound but it doesn't work. It doesn't work in-game, neither in replay.

I also have the kiai, win, and dq sounds, and they work fine. My grip sound is in the "wave" format, as are all my other sounds. It is only 1.5 seconds long, and I got a message saying it uploaded fine. Is there something I don't know about grip sounds? Any help would be greatly appreciated.

Thx,
