can not clean songs

since i upgraded my laptop to OS X yosemite it’s not allowing me to clean my any of my songs it’s saying "One or more of these songs are in an unsupported format and cannot be processed. TuneUp supports locally stored audio files in MP3 and DRM-free AAC (MP4).” but i tried cleaning a song i clean before when i was on maverick and it’s saying the same thing
