Mom gave me her reader
I have a Sony reader that I use often. My kids have started using it a ton too so my mother gave me hers which she doesn't use. When I connected it to my computer and tried to transfer a book from my library onto the "new" reader I got the message "This eBook cannot be transferred because the Reader is authorized to another user". Ho do I get past this? Do I need some sort of user information from my mother? Do I need to re-register it? Any help would be appreciated.
