Since I updated to iOS 7, my OverDrive Media app crashes every time I try to use it. What to do?
This is already a known issue with the app crashing on iOS 7, they'll put out a fix soon.


  The upgrade to iOS7 has resulted in problems for many OverDrive Media Console users.
  
  We are working on getting a new version into the App Store. If you do
  not want to wait for the fixed version, you can complete the following
  steps -- but note in advance that they are not ideal as re-installing
  will clear your bookshelf, history, and app settings...
  
  
  Uninstall OMC.
  Re-install OMC.
  Re-authorize your device with your Adobe ID when prompted.
  Download your title(s) again.
