Performed illegal operation - Fixed with DirectX 8.0

[kstaples]

I just installed khpro. I tried to use it by adding a wave file and text file that I had prepared. When I press start,
I get the "illegal operation window" and am dumped out. I tried using the goldenwave program to extract another wave file and had the same results. I uninstalled directcd but have createacd still installed as well as musicmatch jukebox and realplayer. I have seen other similar posts. How can I ensure that my wav file is not the problem? and if it is the problem, how can I make sure future files are good?
