I have a Kobo, and I am having the same issues. Never had this problem before now. Its been a few months since I borrowed from the library. Error message "CE_COPY_NOT_ALLOWED no permission to copy this book. I have a PC, Adobe Digital Editions 4.0 installed. I have downloaded ebooks from my online library, of which the purpose is to load onto my KOBO, but I get this message. I tried 5 different books, all do the same. And of course I have permission to copy this book.
