Ok I recently un-installed and re-installed Canola2 and now it doesn't see my music files.

I've tried un-installing again and removing the whole .canola directory and then re-installing, reselecting the location of the music (removable card/music) it goes through the refreshing media library, and then if you go back in the folder is unchecked again (I've verified the music there is playable with other media players.

As an add-on I'm still having the problem even after reloacting the music to a different folder/card.
