Hi there! Great application. Just downloaded it and started using. But something seems wrong (well, maybe I'm doing something wrong). When I click "Settings" and then "groups", I see the groups list with all the "Ring Tone" fields stating "disabled". Then when I click one of them to select a ringtone it opens the audio-clips folder, but the list is always empty (but I have a lot). How can I select a ringtone?
