Latex stopped creating a bibliography after updating the system [closed]

Question

I use vim with with vim-latexsuite and TexLive. I use the .sty and .cls files, respectively the whole package date 2012-05-10 from the university of Hagenberg Link to zip package.

Till yesterday everything works like a charm which means that the document including the bibliography was build as intended.

Today I updated my notebook to vim 7.3, vim-latexsuite 20121118-1 and texlive 2012.28273-1.

I tried to compile my main file but the document doesn't either show a bibliography nor references in the text. I have no idea why the bibliography cannot be resolved.

I devided the information I have into two sections.

In section 1 I try to show the relevant parts of my main, [sty] and cls document.

In section 2 I try to show the relevant parts of the log files.

// Section 1 / main-file

\documentclass[bachelor,german]{hgbthesis}
\AddBibFile{literatur.bib}  % Angabe der BibTeX-Datei; is a wrapper for \addbibresource defined in .cls

\begin{document}

\include{cha1}
\include{cha2}

\MakeBibliography{Quellenverzeichnis}  %defined in .cls

\end{document}

/ .cls-file (hgbthesis.cls) - extract

\usepackage{csquotes}   % recommended for biblatex
\usepackage[style=numeric-comp]{biblatex}[2011/05/12]
\ExecuteBibliographyOptions{sortcites=true,defernumbers=true,isbn=false,doi=false}
\newcommand{\MakeBibliography}[2][]{
% opt. arg (#1): optional argument "nosplit" to get a 1-piece bibliography
% req. arg (#2): main title of bibliography
\clearpage
\ifthenelse{\equal{#1}{nosplit}}%
    {% create a single bibliography with all entries:
        \printbibheading[heading=bibintoc,title={#2}]
        \begin{bibhyphenation}  
        \printbibliography[heading=noheader]
        \end{bibhyphenation}
    }
    {% split the bibliography using the predefined categories:
        \printbibheading[heading=bibintoc,title={#2}]
        \begin{bibhyphenation}
        \printbibliography[filter=literature,heading=subbibintoc,title={\@bibtitleLiteratur}]
        \printbibliography[filter=avmedia,heading=subbibintoc,title={\@bibtitleAvmedia}]
        \printbibliography[filter=online,heading=subbibintoc,title={\@bibtitleOnline}]
        \end{bibhyphenation}
    }%

// Section 2

I did a backup of the whole directory thus I compared the aux file and had a look in to the .log and .blg file.

// .aux files / old - correct .aux file

\@writefile{lot}{\defcounter {refsection}{0}\relax }\@writefile{lot}

I found no \citation commands---while reading file cb_MainFile.aux

Citations in my document look like this:
