I am curious about something. Please note, this is not a criticism, it is simply something I'm wondering about. I read in the Bookport manual that the Bookport can in fact play digital talking books from RFB&D. However, no mention is made of the process by which one can activate the Bookport so that it can play such books. I realize that the process is not in fact referred to as activation, but what exactly does one have to do? Inquiring minds want to know.
