That error message could mean a couple things:


1. You may need to activate Adobe Digital Editions on your computer by creating an Adobe ID and password, and then logging into Adobe Digital Editions to authorize it; see http://uhcl.libguides.com/ebookhelp/ade#s-lib-ctab-5784888-1

2. If you have already created the ID and authorized Digital Editions, try these instructions to de-authorize and then re-authorize Digital Editions: https://helpx.adobe.com/digital-editions/using/authorizing-and-de-authorizing-adobe-digital-editions.html
