This issue has been happening more and more.
You locate the Custom Folder in the Toribash Folder, find your Username and delete the Kiai File. (I have a Mac so I wont go into Folder Specifics).
However, if that doesn't solve the issue. I have had several incidents now of certain .wav files simply being incompatible with the Engine for whatever reason.
If replacing it doesn't work. You can always PM me to have the file personally replaced by me.
