Error message when converting from ZIP to ePub

[luthar28]

I am using Calibre 0.8.2 -- on Windows 7. I've just upgraded from Windows XP where I haven't had any problems.

My first book was great. Second...it won't convert it...I get an error message. I've tried running it without any metadata, or any TOC...as base as possible but no luck.

This is the error -- most of it means nothing to me! Any ideas?

calibre, version 0.8.2

I JUST found the problem.

I had an undeclared DIV (no corresponding class in the stylesheet). I erased that...and no probs!
