I don't know what is going on, but I've moved computers and my biblatex bibliography no longer gets printed.
I do the usual:
\addbibresource{references.bib}
\nocite{*}
...
\printbibliography
\end{document}
I am using TeXworks and click on the play button with the "pdfLaTex" selected. But there is no bibliography that gets generated! All it says is:
54 LaTeX Warning: Empty bibliography on input line 54.
which is the line that says \printbibliography.
I am using Windows 7. I tried MikTeX, and just tried TeXworks (from TeX Live) – same thing.
I have no idea what's going on, any help?
