I have installed Adobe Digital Editions 4.0, made an account and downloaded some books.
Then i've linked my e-reader to the same account and transfered the books to the e-reader.
I see the icons of the books in the library of my e-reader, but i can't open them, it says: "This file cannot be opened. This document is protected by Adobe Digital Rights Management (DRM) and is not available with your Adobe ID. Log in with the authorised Adobe ID and try again."
I am able to read the books on my computer, but not on my ereader, while I use the same account.
Can you help me?
