I have purchased a number of books from CBD & have downloaded them to ADE. When I tried to put them on my kobo I got an error that said CE_COPY_NOT_ALLOWED no permission to copy this book. Does anyone know what the problem is? I have gotten books from this place before and had no problem putting them over to my kobo.
If you right click on the book in Adobe Digital Editions and open the menu item "Item Info" you should be able to view the permissions for the book. The books you have purchased more recently may not have the same set of permissions as the books you previously purchased.
I would start there and post the permissions that are set on the book, that might help us determine what the problem is.
