When connecting the reader to the PC after installing Adobe Digital Editions I was asked if I wanted to authorise or not the equipment and erroneously I said NO and to not ask me anymore. Now, when passing a recently downloaded ebook from the PC to the reader I cannot open it because of DRM. How do I solve the problem?
Authorize Digital Edition with your Adobe ID and ask for reseller if your can get the eBooks new. This are linked now with the empty authoize and can read only on this device.
