I was trying another books, and I think that the problem is just with a concrete book. It has cover, and it is showed at the main menu and when I open the book, but for some reason, screensavers hack doesn't like this cover, and doesn't use it, so the image it shows is that from the previous book I opened.
Thanks for your help, NiLuJe.
