Doesn’t work on Mac OS X Yosemite(?)

Not sure what’s going on with this app. I’ve got both .wav files as well as .m4p files and neither will play. Fortunately, no money loss, but still. The app loads fine and and I can drag & drop tracks to the platters, but from there it lists “error” and won’t play the tracks. Issue with OS X Yosemite, perhaps?
