I have the latest edition of ADE, which I installed on this computer running windows 10. Just double-checked my ADE ID to make sure that it matched with the computer running windows 7 that shows the purchased books. I deauthorized and reauthorized ADE, but that did not work.
What do I need to do to get my books?
Syncro at moment not right work. Only with Mobile Device to Hardware Device at moment. If you want the eBook you remove the My Digital Edition folder under My Documents from the old Device to the new device. Or Download the eBooks of the Website of the reseller.
