Thank you for your response! I was actually able to download Calibre and use it with my SONY Reader. Then, I went to
www.booksonboard.com and downloaded a book. I can view the book on my computer by using Adobe Digital Editions. When I load the book onto my reader through Calibre, it won't show the pages of the book because it says it is protected by DRM. But, I paid for the book, and I am able to view it on my MAC, just not on the reader. Do you have any advice for me? It would be much appreciated! Thank you! Michelle
