CORS with 3.62 and mp3 file streaming

I have successfully created CORS for all my applications and they are all working ok (VOD, Live Streaming), but my streaming playback of mp3 files is getting the CORS error even thought it has the same settings. My mp3s are in different subfolders so I wonder if that has something to do with it - is it an instance thing?

It must take a while for the settings to take. I had restarted the Wowza service twice but it was still giving me a CORS error. Went to lunch and came back and then everything worked.
