This question already has an answer here:

Today I encountered an issue with biblatex and it seemed I had to update the biblatex package to the newest version to fix this.

So I went for a complete update of my MikTeX installation (installed all possible package updates... maybe that was a mistake, dunno). I knew I needed the newest biber (1.7) then, so I downloaded that. Log says biblatex is v2.7a. On the way I also updated to the newest apa6.cls and to TeXnicCenter 2.02 stable (32-bit on Win 7, used a beta before).

Before doing all this stuff, everything compiled properly... but now I get these Warnings like citation undefined... empty bibliography, undefined references etc. Any help would be highly appreciated!

Here is my TeXnicCenter config of biber:

Here is the working example, notice that I got backend=biber:

\documentclass[man,12pt,a4paper,noextraspace,donotrepeattitle,longtable]{apa6} % 12 pt., doppelter Zeilenabstand usw.

\usepackage[latin1]{inputenc} % für ä,ö,ü,Ä,Ö,Ü,ß usw.

\usepackage[english,ngerman]{babel}

\usepackage[T1]{fontenc}      % für exakte Darstellung von Umlauten wie Ä

\usepackage{lipsum}           % Dummy-Text
\setlipsumdefault{8}          % Standard-Einstellung: Verwendung nur eines Lipsum-Paragraphs (in diesem Fall des achten)

\setlength{\LTleft}{0pt}      % linksbündige Tabellen (longtable)

Edit: The .bib content I am citing in this example:

    author={Colin MacLeod and Elizabeth Rutherford and Lyn Campbell and Greg Ebsworthy and Lin Holker},
    year={2002},
    title={Selective attention and emotional vulnerability: Assessing the causal basis of their association through the experimental manipulation of attentional bias},
    journal={Journal of Abnormal Psychology},
    volume={111},
    number={1},
    pages={107-123},
}

Edit2: I don't know if this is helping... the biber log:

Can you report the contents of the .blg file the run of Biber produces? –  egreg Oct 8 '13 at 21:59
    
How do you open a .blg? Windows says it is a "performance monitoring" file ("Leistungsüberwachung" in german) which is usually opened with something like a monitoring program. But nothing can be seen there. If I open it with TeXnicCenter there is only: "[0] Config.pm:425> INFO - This is Biber 1.7 [1] Config.pm:428> INFO - Logfile is 'Arbeit.blg'" –  entne Oct 9 '13 at 7:41
    
solved - I will create an answer –  entne Oct 9 '13 at 10:02

Sometimes you find the solution not until having posted a question...

This was the solution (the bottom part of the answer about biber's temp cache).
