Still not working. I tried installing the newest version of Calibre (after uninstalling what I had) and made no changes to anything. This time I added a totally new book, one I'd never converted from html to anything. Same result, but the error message was a little different. It detected chapters, but then Python terminated (see below). I hate to keep fussing like this, but it's always been such a dependable program, and I'm really frustrated. I do appreciate your help.
