We're sorry you're having trouble with Adobe Digital Editions (ADE). The error you're receiving can be caused by one or more of the following system settings:

  1. Incorrect clock time.
  2. Incorrect date.
  3. Incorrect time zone.

Carefully check your device's system time, date, and time zone to verify that they are correct in relation to your location. You can access time settings by clicking or double-clicking on your clock. When these are properly set, you should no longer experience this error.

If the timestamp on the ACSM doesn't match the current time, then the activation server assumes that the title has expired and you can't download the eBook. Because these ACSM files expire, you can't open an ACSM file that has been saved on your computer from a previous session.

To avoid trouble, delete any saved ACSM files and clear your temporary internet files. Once you've done that, you can download titles from your library website under your account at any time during the lending period. When you download the ACSM file, be sure to open it right away so you can download your selection without issue
