This is a very basic problem that probably has a really simple answer but its pissing me off. I am trying to make a ringtone in Garageband using a track from itunes. However, when I put the track in it didn't show up and when I finally got it to show up it said it had to create a Garageband preview then the preview had no sound on it at all when I played it. Then I figured out i have version 3.0.4 (?) so i tried to update it to 4.1.2 but it said "An eligible Garageband application was not found in /Applications." Please, what do i do?
