How To Change the Authorized Adobe ID
http://www.adobe.com/go/digital-editions-createID
What do you do if your copy of Adobe Digital Editions is authorized with the wrong Adobe ID? This can happen if you’ve started using a different Adobe ID or you somehow messed up the authorization in the past.
If you’re trying to open an ebook when Adobe Digital Editions is authorized with the wrong Adobe ID, you’ll get an error message like: “License fulfilled by a different user” or something similar referencing licensing or authorization.
Important note: If you have some ebooks that do require your current authorization, those will become unreadable if you authorize with a different Adobe ID.
deauthorize
The first thing to do is deauthorize Adobe Digital Editions. This will remove your current authorization.
1. Open Adobe Digital Editions
2. On your keyboard, simultaneously press the Ctrl, Shift, and D buttons (if on Windows) or the Cmd, Shift, and D buttons (if on a Mac)
3. Click the “Deauthorize” button
After this you should close Adobe Digital Editions, and then open it again.
re-authorize
If you’ve followed the steps above, your copy of Adobe Digital Editions is no longer authorized.
Open Adobe Digital Editions
Adobe Digital Editions will behave as if you’ve just installed it, and will prompt you to enter your login information for your Adobe ID. Use the Adobe ID account information that you want to use to authorize Adobe Digital Editions.
