    Hi Newestguy,

    You need to manually delete the activation file and then resign in. Please follow these steps:

    You must have administration authority.


    On Windows it can be found here:
    Open Windows Registry by using the command prompt and typing 'regedit' or by opening the start menu and searching for 'regedit'.

    Search for the following folder:
    HKEY_CURRENT_USER\Software\Adobe\Adept\Activation

    The 'Activation' folder can be entirely deleted.

    On Mac it can be found here:
    In Finder, find the 'Go' option on the menu bar and click 'Go to folder' and type the following in:


    ~/Library/Application Support/Adobe/Digital Editions/

    Delete the activation.dat file within the 'Digital Editions' folder.

    Restart ADE and it should be deactivated at this point. You should be good to sign back in.
