Ok, re-adding just the html file worked. I'm betting that is the problem with most of my conversion failures.
Is there any better way of handling that in the conversion script? Or, at least, an error message that was more user friendly?
In my code, I just exit and continue when an error isn't fatal to the whole process.

Or maybe an opf file repair utility?
I'm looking at about 125+ files that didn't convert, and no easy way to fix that won't take a lot of time.
