Deauthorized adobe digital editions, reauthorized without id or password, now trying to reauthorize with id and new password and message comes up saying "you can only authorize this computer with Adobe ID that has not been used to authorize other computer

How do I reauthorize my computer now?

This all started because my kobo ereader kept giving message saying your ereader is not authorized to open this book.

Thank you.
