The MIDI file in the DigiTrad doesn't play. When I tried to save it and listen to it in Noteworthy, I got an ominous message saying "There is a serious problem in the something-or-other. It is recommended that you save your work ASAP."

Can somebody fix this?

I want to see if this tune is the same as the "Follow me Down to Carlow" that I sang in high school.
