This evening, I attempted to transfer my first RFB&D book to the Book Port. On my pc, I have RFB&D's TPB reader software installed for listening to their books. Books are activated, of course, by entry of a 4-digit numeric code. When I attempt to have the BP transfer software transfer the book, all I can transfer is RFB's protective notice. I am not prompted to enter that same 4-digit code. So am I doing something wrong, or do I need a 2nd security code to get the job accomplished?
