Reset covergloobus settings

I have covergloobus installed but cant see it. Dont know if it is the theme i had (i had a theme that disables or gets invisible when no music is playing) and by mistake i select other music player for covergloobus. So it now only display coverart when music player is playing music. But the problem is i dont know what music player is... I also have the covergloobus tray icon desactivated so i cant go to settings..

Any ideia?
Uninstall and install program didnt work.

Thanks in advance,
Pedro
