I am using ADE to transfer books to my Kobo e-Reader but have had to reinstall it a few times on the same computer.
Now it's telling me it's authorised on too many computers and won't authorise me to move the books.
How can I de-authorise it so I just have one working copy ?
You can contact Adobe tech support via chat. They should be able to tell
you how to submit the request. But beware! Not all chat agents know this
- so be persistent.
