You can run a backup (Settings>backup) so any user songs and playlists are saved. Send the email to yourself. Uninstall the app, long-press on the iReal book icon and when all apps jiggle, press the X on iReal book to delete, then press Home button to return to normal mode on your iPhone.

Download iReal book again from the app store (you will not charged again).

Also you could turn off your phone completely, then back on again to clear any memory problems that might be causing problems in overall running.


We are interested in what you were originally doing just before the sort crashed. Can you remember? Were there user songs and library songs in it. Any with strange titles using odd type characters for instance?
Any information you give us might be helpful to track down the problem.
Thanks.

Or the problem could be in the song you are importing in some way, but try reinstall first.
