Problema con BibLaTeX e la classe sig-alternate

::

Ciao,

per un articolo mi serve la classe sig-alternate. Fino a ieri non avevo nessun problema con la bibliografia, ma dopo aver aggiornato TeXLive 2012 questa mattina non riesco più a creare la bibliografia.

Ho creato il seguente esempio (non proprio minimo in quanto ho lasciato gli stessi pacchetti che carico nell’articolo):

`
\documentclass{sig-alternate}

\usepackage[T1]{fontenc}
\usepackage{textcomp}
\usepackage[utf8]{inputenc}
\usepackage[english]{babel}
\usepackage{microtype}
\usepackage{xcolor}
\usepackage{booktabs}
\usepackage{tikz}
\tikzset{every mark/.append style={scale=0.55}}
\usepackage{engtlc}

\usepackage{filecontents}

\begin{filecontents*}{biblio.bib}
@ARTICLE{bowman:reasoning,
AUTHOR = “Mic Bowman and Saumya K. Debray and Larry L. Peterson”,
TITLE = “Reasoning About Naming Systems”,
JOURNAL = “ACM Trans. Program. Lang. Syst.”,
VOLUME = {15},
NUMBER = {5},
PAGES = {795-825},
MONTH = “November”,
YEAR = {1993} }
\end{filecontents*}

\usepackage[babel]{csquotes}
\usepackage[bibstyle=numeric,citestyle=numeric-comp]{biblatex}
%\bibliography{sigproc} sample
\bibliography{biblio}

\usepackage{hyperref}
\hypersetup{%
colorlinks,
linkcolor={black},
citecolor={black},
urlcolor={black}
}

\begin{document}

\title{title}

\author{

\date{August 2012}

\maketitle

\begin{abstract}

\end{abstract}

\section{Introduction}

\section{Previous work}

% Bibliography
\nocite{*}
\printbibliography

\end{document}

Dopo pdflatex main.tex, il passo bibtex main.tex mi restituisce:

`
I couldn't open file name `main.tex.aux'

Spulciando il [tt]log[/tt] mi sono imbattuto in:

A che cosa può essere dovuto il problema?

Grazie,
