How to make a ringtone from a Protected ACC file

[AnimalPaintball]

Im using Garageband 08, but when I go to the media browser to select the song, the song does not show up. Im guessing because it is Protected.

Any ideas?
Thnx

Its because it's a protected file.

I'm not even sure Garageband can do it with a regular AAC file either. Works fine with mp3 files though.
