DOES NOT WORK IN YOSEMITE

Purchased app to batch rename ID3 music file names with metadata stored on file. Worked for a total of 13 files before it stopped working. Tried renaming individual file - didn’t work. Tried restarting program - didn’t work. Tried restarting computer - didn’t work. Acts like it is working but nothing happens. I want my money back.
