When I try to typeset a book I?m writing however, it gets stuck on chapter 2. The strange thing is that I haven?t touched chapter 2 in months. Here?s the relevant (I think) part of the console log:

	Thanks, Herb and Ross, for the reply. I ran the exact same file on a different machine and it typeset without problems. So I reinstalled MacTeX on the new iMac, but got the same error again on the first typesetting. It doesn’t make much sense to me that the problem only occurs on a particular machine.

	Forgetting this for the moment,  the problem seems, as Ross says, to be related to citations (no, I am not using any special package for citations): I deleted the citation "\cite{HS74}” (mentioned in the error message) from the document, ran it again, and got the exact same error message complaining about a different citation this time.

	Now, I know next to nothing about how to deal with citations, so let me describe the setup briefly. I have a file, “diffgeom.bbl”, where I’m gradually putting all citations. The root document, “diffgeom.tex”,  basically contains the preamble, the \frontmatter with the preface and a line
"\nocite{*}%prints all bibliography"
(don’t ask me why). Next, another line “\tableofcontents", then the “\mainmatter" which inputs the separate chapters (“\input{Chapter1}”, etc). Finally, the “\backmatter" line, followed by:
"\printindex

\bibliographystyle{plainnat}
\bibliography{diffgeo} 
\end{document}."

	That’s it. I have no idea why the \bibliography entry says “diffgeo” instead of “diffgeom”, but it doesn’t seem to matter. The same error occurs if I replace it with “diffgeom”.

	Thanks again,

	-Gerard
