I've ebooks borrowed from the library on digital editions. But when I connect my Sony ereader to the computer, it is not showing in digital editions. I can drag the books in finders from the files to the ereader, but instead of them being in DCIM, they are in the media files and the ereader is not recognising the books as legitimate. The reader icon also didn't show when I use Reader for Mac apps recommended by Sony. I've done hard reset and reinstall the softwares but nothing works. Can someone help please?
