The document is as follows:


\documentclass[12pt]{article}
\usepackage{geometry} \geometry{a4paper}
\usepackage{pdfsync}
\usepackage{ifpdf}
\usepackage[T1]{fontenc}
\usepackage{gtamachoefler}
\usepackage[round]{natbib}
\def\myauthor{Mark Eli Kalderon}
\def\mykeywords{Boghossian,, relativism,, epistemic, relativism}
\def\mytitle{Epistemic Relativism}
\ifpdf \pdfoutput=1
\usepackage[ plainpages=false, pdfpagelabels, bookmarksnumbered,  
pdftitle={\mytitle}, pagebackref, pdfauthor={\myauthor}, pdfkeywords= 
{\mykeywords} ] {hyperref} \fi
\title{\mytitle}
\author{\myauthor}
\begin{document}
\bibliographystyle{plainnat}
\bibliography{Philosophy}
\end{document}

It is more or less the standard preamble that I use and I have never  
encountered any problems before. I am beginning to suspect that there  
is, somehow, a problem with my TeX install since I can't see what  
could be going on. I might try just rebuilding at this point. Thanks  
for all the help. Best, Mark
