George, I uninstalled/re-installed....no help. I still couldn't get a track to load in Microstudio as you suggested. I tried the cdg, bin and wav. I guess I haven't mastered the learning curve yet. However, in my frustration to find something to fix my problem, I downloaded the khpro v4107 update and although the enhancements did not appear to have anything to do with audio problems, voila! it seems to have corrected mine. I don't know what it could have changed in relation to audio, but for now, the problem has corrected itself. Thanks for your help
