This is what we try first when one of the digital book apps is not working properly on our iPad. It solves all general issues. Restart the Device: Restart your device about once a week for best performance. 1. Hold down the power button on the top right corner of the device until a "power off" message appears. 2. Swipe the power off slider to fully turn off the device. 3. Allow the device to be off for a minute or two before turning it back on and trying the app again. Uninstalling/Reinstalling App If restart does not work. 1. Go to the home screen of your device, and hold down on the misbehaving app until it starts to "wiggle." 2. A black X will appear on the corner of your app. Tap this to delete it. 3. Tap your home key to exit deletion mode. 4. Reinstall the app from your App Store. If you need instructions on doing this, see the Tutorials page. Apps for Cloud Library - checkouts will reappear after login to the app. Reader Apps for Enki or Freading - download a fresh copy of the book from My Account (Enki) or My Downloads (Freading).
