I have tried downloading and uninstalling several times. I have tried to deactivate authorization and it says try later. I am on a MacBook running 10.13.6. I have tried going to ~/Library/Application Support/Adobe/Digital Editions/ and there is no such file in order to delete the activation.dat file. I have tried the 3.0 version as well. I am not sure what to do next. Can anyone offer some insight?
Close all applications.
Press WINDOWS + R.
In the Open text box, type regedit and then press Enter. The Registry Editor opens.
In the left pane of the Registry Editor, locate the following registry key: HKEY_CURRENT_USER\Software\Adobe\Adept
Remove the Adept Folder.
In the Confirm Key Delete dialog, click OK.
Close the Registry Editor.
Open Adobe Digital Editions and reauthorize..
quit Adobe Digital Editions.
Navigate to /Users/Library/Application Support/Adobe/Digital Editions and drag the activation.dat file to the trash.
