I've come across 2-3 books that need the latest version of Kindle to be read. If I keep Epubor running in the background then those books don't get downloaded. If I close Epubor, only then Books get downloaded, but then Epubor isn't able to remove DRM and asks me to delete the ebooks and re-download the book, while keeping epubor running in the background.
But running the Epubor in the background doesn't let me download the books... Are you getting me ?
Thank you for contacting us. Yes, I got you. That's because your kindle books can only be downloaded via the latest kindle app. And this is decided by the Publisher and cannot be changed. We are sincerely sorry to inform you that this kind of ebooks can not be decrypted because they are encrypted with tougher kindle drm.
We are sincerely sorry for the inconvenience caused.
To use download and transfer via usb method, you at least should have one kindle eink device registered with your account information.
If you cannot find via usb option, that's because you have no kindle eink device registered.
