All I can think of is that in using a find and replace command I'm killing some code I needed?

I get one of two messages- the first is when trying to open a file in Adobe Digital editions:

calibre, version 3.2.1
ERROR: Could not open e-book: Failed to read book, C:\Users\Jon\Documents\Calibre Library\Unknown\PEN EPUB D (162)\PEN EPUB D - Unknown.epub click "Show Details" for more information

ValueError: C:\Users\Jon\Documents\Calibre Library\Unknown\PEN EPUB D (162)\PEN EPUB D - Unknown.epub is not a valid EPUB file (could not find opf)



I get this when trying to open in Calibre (from which it was saved).

calibre, version 3.2.1
ERROR: Could not open e-book: Failed to read book, C:\Users\Jon\Documents\Calibre Library\Timothy J. Gawne\OLD GUY AND THE PLANET OF ETERNAL N (159)\OLD GUY AND THE PLANET OF ETERN - Timothy J. Gawne.epub click "Show Details" for more information

You must have deleted your opf file export your ebook using calibre's save to disk fuction, then unzip it, then import the html toc file--not the toc.ncx--into calibre--you do have a html toc--, then do a zip to epub conversion.
