How to use biblatex with miktex and texmaker [closed]

Question

I try to write my thesis with LaTeX. I built a basic template which seems to work. But, now I want to use biblatex for autor-year citations. And this doesn't seem to work in my case. I'm getting errors which makes no sense to me.

These are the error-messages which texmaker shows me:

And this is my code:

%-------------------------

\section{Fazit}

%-------------------------
% Literaturverzeichnis

\pagenumbering{Roman}
\setcounter{page}{\value{savepage}}
\newpage
\printbibliography

\end{document}

Here is the relevant biblatex code:

\usepackage[backend=biber,style=alphabetic,citestyle=authoryear]{biblatex}
\addbibresource{literatur.bib}
\begin{document}
\section{Grundlagen}
Hier steht ein Zitat \cite[S.102]{wurst}.
\printbibliography
\end{document}

And the literatur.bib:

% This file was created with Citavi 5.2.0.8

@book{wurst,
 author = {P{\"o}hm, Matthias},
 year = {2015},
 title = {Pr{\"a}sentieren Sie noch oder faszinieren Sie schon? Abschied vom {\dq}Betreuten Lesen{\dq} ; emotionale Rhetorik statt PowerPoint!},
 address = {Bonstetten},
 edition = {3. Auflage},
 publisher = {{P{\"o}hm Seminarfactory}},
 isbn = {3952395048}
}

Furthermore, I got a strange page on top of my titlpage. There are some letters like "anytanyt".

If I use the bibliography package with basic settings there are no erros and all is fine, but I need the autor-year citation. I think this is some sort of misconfiguration. But I don't get it :(.

Using Texmaker 4.4.1, MikTex 2.9 and Windows 10

UPDATE:

This is my logfile main.blg after compiling with biber.

UPDATE:

I tried to update and synchronize my MikTex installation (it's completly new downloaded but ok...)

This is the result:

Slowly i get tired about using Tex. Maybe it's better to use a Linux VM?

UPDATE

The internal error which occurs if i start Update-Wizzard in Package-Manager:
