Adobe Digital Editions: Some Problems Reported

This blog post is for those of you who typically download EPUB eBooks to your computer to transfer to your Nook eReader. Not that not all Adobe Digital Editions users are affected.

If you are running Adobe Digital Editions 4.5 and are receiving a message that reads:

IO Error on Network Request. Please check your network connection and try again.


Update: 

After having a similar problem after installing an earlier version of ADE, I recommend the following: 
  • Deauthorize ADE and reauthorize the computer.
Tips: 
  • Find out the email address used to create the Adobe ID: Help >> Authorization Information. 
  • Deauthorize your computer. 
  • (Windows: Ctrl + Shift + D)
  • (Mac: Command + Shift + D)
  • If you are not sure about your password, try signing in on Adobe.com and reset your password, if necessary. (Doing so on from a webpage is *much* easier.)
  • Once you are certain about your password, reauthorize the computer from Help >> Authorize Computer. 
I no longer recommend installing an older version of ADE for this issue as a first step. Only use these instructions if the steps above do not work. 
  • Uninstall Adobe Digital Editions 4.5. 
  • Install version 2.x or 3.x from this Adobe page
  • Checkout and download a new title. 
  • Contact your local librarian if the problem persists. 




Advanced Steps to Take:

One of our NH public librarians was only able to resolve the problem by taking more advanced steps. Please take care if attempting these instructions. Adobe states the following about editing the registry: 
Disclaimer: The following task requires you to modify the Windows registry. The registry contains system-related information that is critical to your computer and applications. Before you modify the registry, make a backup copy of it. Adobe doesn't provide support for problems that arise from improperly modifying the registry.

  1. Quit Adobe Digital Edition.
  2. Choose Start > Search for regedit (On Windows 10: it’s in c:\Windows directory)
  3. Right click on regedit, ans select “Run as admininstrator”
  4. In the left pane of the Registry Editor, locate the following registry key: HKEY_CURRENT_USER\Software\Adobe\Adept
  5. Select “Adept” , right click on it and select “Delete”
  6. In the Confirm Key Delete dialog, click OK.
  7. Close the Registry Editor.
  8. Open Adobe Digital Editions and reauthorize (Help->Authorize Computer…).


I hope this is helpful!
