Biblatex: Bibliography for minimal Example doesn't appear in the PDF [closed]

i want to use the solution provided in Biblatex: Adding time information to "online" field and a label in front of url I tried to launch the minimal example provided by Guido but the Bibliography isn't appearing in PDF file. I made a new Tex file and inserted this

\documentclass[a4paper,
oneside,
12pt,
bibliography=totocnumbered,
listof=totocnumbered
]{scrreprt}
\usepackage[english, ngerman]{babel}
\usepackage[utf8]{inputenc}
\usepackage[babel,german=quotes]{csquotes}
\usepackage[automark]{scrpage2}
\usepackage[]{url}

\usepackage[backend=biber, style=authoryear, urldate=comp, dateabbrev=false]{biblatex}
\bibliography{source.bib}

\begin{filecontents}{biblatex-dm.cfg}
\DeclareDatamodelFields[type=field,datatype=literal,skipout=false]{urltime}
\end{filecontents}
\DeclareFieldFormat{urltime}{#1}
\DeclareFieldFormat{urldate}{%
\iffieldundef{urlday}
{}
\iffieldundef{urlmonth}
{}
\printfield{urlyear}%
}

\renewbibmacro{url+urldate}{%
\printfield{urltime}}

\AtEveryBibitem{\clearfield{month}}

\begin{document}
Latex is science \parencite{stack}

\clearpage

\printbibliography

\end{document}


Then i made a source.bib file and entered this:

@online{stack,
author = {Stack},
title = {Why {\LaTeX} is science},
month = {april},
year = 2012,
url = {www.tex.stackexchange.com},
urldate = {2013-04-29}
}


I use a portable TexMaker. What am i doing wrong? Thanks in advance

Edit: it appears when i delete the argument backend=biber the bibliography is visible. Maybe there is something wrong with my TexMaker.

Edit2: I make sure both my files (.tex and .bib) are saved, then compile PDFLaTeX BibTeX PDFLaTeX PDFLaTeX and show pdf

in options\Configure Texmaker there is for PDFLaTeX : "../miktex/miktex/bin/pdflatex.exe" -interaction=nonstopmode %.tex BibTeX : "../miktex/miktex/bin/bibtex.exe" %.aux

Compiler says process exited normally every time but there are some blue (minor i guess) errors like:

LaTeX Warning: File biblatex-dm.cfg' already exists on the system.
LaTeX Warning: Citation 'stack' on page 1 undefined on input line 49.
[1
{C:/Users/as24707/Documents/latex_portable/latex_portable/miktex/pdftex/config/
pdftex.map}]

)

Package biblatex Warning: Please (re)run Biber on the file:
(biblatex) Test1
(biblatex) and rerun LaTeX afterwards.
Package logreq Info: Writing requests to 'Test1.run.xml'.
)


Edit3: My TexMaker is version 1.9.9 wich is outdated. Im trying to set the 4.1 running. Im gonna check back later to let you know how it went. Thanks a lot for all the help so far:)

Edit4: Ok im still far from ready. I installed portable versions of Miktex and Texmaker. Entry at Bib(la)Tex : Biber % doesnt work so i klicked on the blue foldery button an browsed for Biber file. Now it looks like this "C:/Users/as24707/Documents/latex_portable/latex_portable/MikTex/miktex/bin/biber.exe" %

when i use f11 on my actual document i get notification that i should use biber (my file is not properly adjusted jet). On the MWE from the topic above i use f11 and get following log

You have to change bibtex % in your settings to biber %` Biblatex + Biber + Texmaker + MiKTeX or texwelt.de/wissen/fragen/1909 Please make sure, that your distribution is up to date. –  Johannes_B Dec 19 '13 at 13:29
Are you sure that TeXmaker is calling the correct (updated) binaries for tex/latex/pdflatex? You've set the path manually for biber but did you make sure the paths are set correctly for everything else? –  cfr Dec 19 '13 at 16:00
The final Washington in the biber log tells you the problem. The version of biblatex you use is too old. You have to update to a recent version. –  Guido Dec 19 '13 at 16:01
This question appears to be off-topic because it is about an old version of the packages software ghost can be solved by an update –  Guido Dec 19 '13 at 18:43
