I have been reading an epub (created from pdf) on my H20, and editing with Sigil on the way, so it is definitely without DRM. The H20 suddenly stopped changing font size, although it had been working fine previously in the same book, so after deleting and reloading the book (via Calibre) with no effect, I powered off and then switched on my H20. Now I can't even open the book as it says it is protected by Adobe DRM when I know for a fact that is has no DRM. I have tried converting to AZW3 and back to epub but the problem remains. Has anybody ever had this happen to them? If so, is there a solution? I am on holiday and I really want to continue reading this book!
