Hey,
I can't seem to figure out how to get my KOBO ebook to work in Calibre or within Koreader on my Kobo device.
I want it in Koreader because of the annotation options available to me there. So as far as I understand I need to DeDRM the book to do that.
It has downloaded as an EPUB. And it Imports as an EPUB in Calibre. But it will not open despite me having DeDRM and OBOK installed.
I keep getting this error message:
Code:
