BibTeX, biblatex and biber ⇒ BiBTex doesn't find any database entries

[sohlin]

Hi,

I have problems with BiBTeX after reinstalling Windows XP on my laptop.

If I take a project that compiles fine on any other computer with MiKTeX 2.7 and try to run it on my laptop, I get the following error message:

Code: Select all

Database file #1: References/References.bib
Warning--I didn't find a database entry for ""

The error appears both in TeXnicCenter and when I run bibtex in the command window. Creating a new project also gives the same error.

There should not be any problem with the .bib or .tex files as it works fine on any other computer. But if it is of any help, the entries in my files are
In the layout file:

Code: Select all

\usepackage[square]{natbib}

In the main file:

Code: Select all

\bibliographystyle{References/autorjahr2}
\bibliography{References/References}

Using \begin{thebibliography} ... \bibitem ... \end{thebibliography} directly in the main file works fine.

Any ideas? I would really appreceate the help.

So, I found a solution to the problem in the following thread

Weird error (package natbib error)

By owerwriting the new natbib.sty (2009/02/02 8.3 (PWD, AO)) with the old one (2007/10/30 8.1 (PWD)) everything works just like before.
