I use Adobe Digital Editions to borrow ePUB books from my local library but would like to read them on a tablet I've just bought which has the Aldiko ereader app preloaded. I can download the books to my computer without any difficulty but when I try to copy them to my tablet I get an error message saying that I do not have permission to copy the book. I thought that as long as I had an Adobe ID i was permitted to use the books on any device I had. I posed the question to Adobe and they suggested that I use the forum so any suggestions would be gratefully received.
Check if you have authorized Aldiko ereader app with your same Adobe ID (email address) which you have used to borrow ebooks from Library and authorized your Adobe Digital Editions on your computer.
