Can’t get it to work

Tried at least a dozen songs and get the same reply each time: “Sorry…This song cannot be made into a ringtone. You may try again or select a different song.” It might help if it told me why, but no indication at all. And literally EVERY song I try brings the same message. For me, this was a total waste of $1.19
