BibTeX, biblatex and biber ⇒ References shown as Question Marks

[bpas]

Hello,

I have read all the topics about this problem. But I couldn't solve.

I am using Latexian and BibDesk, when I preview my document I only see question marks at citations and blank box brackets. I am taking this warning for all references:

Code: Select all

Package natbib Warning: Citation `Taha' on page 6 undefined on input line 46.

The source code.

Code: Select all

\bibliographystyle{unsrtnat}  % Use the "unsrtnat" BibTeX style for formatting the Bibliography
\addtotoc{References}
\bibliography{Bibliography}  % The references (bibliography) information are stored in the file named "Bibliography.bib"

In "Bibliography.bib".

Code: Select all

@article{Baker:1980dq,
  Author = {Baker, B. and Coffman, Jr., E. and Rivest, R.},
  Date-Modified = {2013-06-08 19:05:12 +0000},

Thanks in advance.

Hard to believe since this is a FAQ and has been discussed many times. A Forum Search should for sure yield appropriate solutions.

And did run latex, bibtex and latex twice more to get everything right? If yes and that doesn't help, kindly prepare a self-contained and minimal example to give an adequate problem description.
