Good App but Help!!! – Ringtones. Review

The app works beautifully and I absolutely love it. I do have some questions though. You see on certain songs it downloads onto the file but when I try to put it in the tone section of my library it shows up blank and will not play. It says the file cannot be opened and the icon shows a blank white screen not one with the iTunes mark and the ring below it. Can someone please help me ASAP?
