Hi, Lin and Tony - I take it you got the Digital Tradition Folksong Player from MusicEase. Am I right? I'm downloading the program at this very moment, and I'll fool around with it and let you know. I'm a little disappointed with the $29.95 price tag, but it does sound like a good program.
I think you probably have to unzip the Digital Tradition tunes before you play them. If that's the case, be careful to put them all in a separate directory/folder so they don't get mixed with other files. If you unzipped just any old place, you'd have thousands of files scattered about. Not a pretty sight.
