Sometimes an error occurs where Adobe Digital Editions (ADE) will open, displaying the title you have just checked out, but will not actually download the eBook. The steps below should resolve this issue (on Windows or Mac).
Create a backup of the original "restore" folder
- Close ADE if it's open.
Go to Documents > My Digital Editions. Rename the restore folder to restore.old.
Note: "Documents" may be named "My Documents."
- Download a fresh copy of the title.
- Open (or run) the newly downloaded eBook (which is an ACSM file).
When you open the file, ADE will pop up and load the eBook you selected.
