When I try to open my eBook, I get an error message saying “This eBook is DRM protected.” What do I do? To protect copyrighted content, many eBooks are equipped with DRM (digital rights management) protection. To read this content, you need an Adobe user account (Adobe ID). In the menu, you will see “Adobe DRM” under “My accounts.” You can set up your Adobe ID information here and authorize your tolino eReader. You can register an Adobe ID free of charge using the quick and easy process offered on the Adobe website.
