Problema biblatex

Il sorgente:
`\documentclass{scrbook}

\usepackage[applemac]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[english,italian]{babel}
\usepackage[style=philosophy-modern,hyperref,backref,natbib,backend=biber]{biblatex}
\usepackage[babel]{csquotes}

\addbibresource{Prova}

\begin{document}
Ciao
\nocite{*}
\end{document}

Il file Prova.bib:
`@book{castellacci:sante,
author = {Castellacci, Carla and Pievani, Telmo},
title = {Sante ragioni. Dal nascere al morire. La mano della Chiesa sulla nostra vita},
publisher = {Chiarelettere},
year = {2007},
location = {Milano}
}
`
L’errore:
`INFO – This is Biber 1.7
INFO – Logfile is 'Prova.blg'
INFO – Reading 'Prova.bcf'
INFO – Using all citekeys in bib section 0
INFO – Processing section 0
INFO – Looking for bibtex format file 'Prova' for section 0
