I can’t open my digital materials in a PDF viewer. What do I do?

Digital materials cannot be viewed in Adobe Reader. Please download and install Adobe Digital Editions. If you have already installed Adobe Digital Editions on your computer and your book is opening with a PDF viewer, try dragging and dropping the URLLink.acsm file on to your Digital Editions window. Alternatively, try right-clicking the URLLink.acsm file and opening with Adobe Digital Editions.
IMPORTANT: Please note that Adobe Digital Editions is not the same as Adobe Reader or Adobe Acrobat.
