This issue sometimes occurs when you're trying to transfer an eBook to your Kobo eReader.

Before you try anything below, make sure you're using Adobe Digital Editions (ADE) to transfer eBooks to your Kobo. If you've been trying to use the Kobo desktop software, that could be what's causing the issue.

Try these steps first

Most of the time, simply resetting your Adobe authorization for your Kobo will fix the problem.

  1. Make sure the date and time settings on your Kobo eReader are correct.
    You should find these in the Settings menu on your device.
  2. Plug your Kobo into your computer with the USB cable that came with your device.
  3. Open ADE on your computer.
  4. Remove the eBook that's causing trouble from your library.
  5. Click on your Kobo from the menu on the left.

  7. Try downloading and transferring the title again.

If you're still having trouble, try a factory reset

If resetting your authorization didn't work, you likely need to perform a factory reset on your Kobo. Please note that when you do this, all of the information you have stored on your Kobo will be erased.

  1. After you've tried all the steps above, back up anything on your Kobo that you don't want to lose. Then close ADE and unplug your Kobo.
  2. Factory reset your Kobo eReader.
    As stated above, this process will erase all of your data. When you sync next, your eBooks should automatically be restored, but please remember to back everything up before performing the reset.
  3. Plug your Kobo back into your computer, then open ADE.
  4. Try downloading and transferring the title again.
