I am using a Mac. I get this same error. HOWEVER, your directions DO NOT work. When I go to "Erase Authorization" I get this message: "Unable to Erase Authorization. Please try after some time."
I have tried several things: completely uninstalled Digital Editions and then Re-installed. Shut down computer. These steps are not working.
How can I erase authorization if it wont let me?
If due to some reason, you are unable to deauthorize ADE, follow the below steps:
Mac: Navigate to /Users//Library/Application Support/Adobe/Digital Editions and drag the activation.dat file to the trash.
( Detailed Steps:
1. Go-> Go to folder.
Go to folder dialog will appear.
2. Type ~/Library/Application Support/Adobe/Digital Editions
drag the activation.dat file to the trash.
ADE will be deauthorized now.
Now Authorize ADE again. )
not working, this is really stupid for adobe, now can't read library books anymore
