I have installed Adobe Digital Editions. Both my Computer and Device were successfully activated. Downloaded a book from the library to ADE. Transferred it to my device successlfully. But I cannot open it on my device. Message says"Oops! This document (it is a book not a document) couldn't be opened. It is protected by Adobe Digital Rights Management (DRM) and is not currently authorized for use with your Adobe ID. Please sign in with the authorized Adobe ID and try again. I tried and still get the same message.Can anyone tell me what I am doing wrong..I have no problem with books I have bought only with this one I got from the library.
I forgot to mention that I have the Adobe Digital Editions 2.0 version installed
