The problem being that some of us can't figure out how to remove the DRM from an ebook. And of course it's against the rules for someone to post how to do it here at the forums. I've done the search for the addons (or whatever the term) for doing so and have never been able to figure out how to get things to work right. And being as questions require answers that can't be given in a forum (for legal reasons) I've been stuck not knowing what would be needed to correct whatever I myself did wrong while trying to remove DRM (for books that I own and that would be for my own personal use only of course).
