This error typically occurs when you're trying to download an eBook to Adobe Digital Editions (ADE). There are two possible causes for this error: either your computer's time, date, or time zone is incorrect or you're trying to open an old ACSM file that's saved on your computer.

To resolve this error:

  1. Check your computer's system time, date, and time zone settings to ensure they're correct. You can usually access these settings by clicking the clock on your computer.
  2. Delete any saved ACSM files on your computer, especially the ACSM files for the eBook that gives you this error.
  3. Clear your temporary internet files.
  4. Download the eBook from your library's digital collection again and open it immediately.
