I can't get Logos to accept my 2nd Kindle (a Paperwhite) email address so as to use the "Send to Kindle" feature. My first attempt to register late last year was fine, and I can send any book to my Kindle Fire HD, but at this point I'd rather this function work with my Paperwhite than my Fire HD (since I've got Logos software on that device anyhow). Any thoughts on how I can add my Paperwhite email account into Logos so as to use the feature?
