I have a book already downloaded to my IPAD and IPHONE; when I open my PC I am not getting the book nor the possibility to download it.
also I tried to download it directly from the seller link to my PC; I am getting the following error:
Error Getting licence_License server communication Problem:
All systems (IPAD, IPHONE and PC) are using ADE with the same ID
You error is a download with the eBook itself. Have you try to download it from the website of the reseller with a other internet Browser?
