I just purchased 3 books from Saxo.com. I used Adobe Digital editions for access. I registred all the books on my ID when I downloaded it to my laptop but apparently my laptop wasn't authorized with my ID so it automatically created a "guest id". The problem is now that the books are not registered on my ADE ID but on the guest ID and are locked to my laptop, so I can't use my books on my homecomputer, mobilephone, tablets and so on, which I really need. Somehow I need to get my books registred on my ADE ID instead of this "guest ID".
