Music will not play anymore
 

I convert mp3 to wav, use vogone to remove vocals when saved the music will not go to kh. I locate it, copy and paste the location and still no music. I've made many karaoke songs, but now the music won't play to sync the words to. I have tryed droping the music location in a folder on kh but it don't show up. I have updated and reloaded everything several times, nothing helps.
How do I fix this?
