few days ago I bought an ebook. I downloaded this ebook before my computer was authorized via my Adobe ID. I was able to read the book on my computer but was not able to send it to my Cybook reader. I am not very familiar with ADE software so I thought that when I will authorize my computer via my Adobe ID, I would be able to copy my ebook to my reader. So I did. As a result I am not able to open the book neither with or without my Adobe ID now. Always this error occures: Error getting licence - E_LIC_ALREADY_FULFULLED_BY_ANOTHER_USER. Is there any solution please? I would really appreciate any suggestions. Thank you very much.
