Thank you, Dominik, installed all those current versions, and now
everything works fine…

I think the problem is, that I did not update biblatex, and I do not
know how to do that – maybe someone could help. In the wiki I can
just
find instructions, how to install biblatex, not how to update. I also
do not know, where to find a current biblatex-version.
You find the current versions at CTAN (Comprehensive TeX Archive
Network):
http://tug.ctan.org/pkg/biblatex
http://tug.ctan.org/pkg/biblatex-dw
http://tug.ctan.org/pkg/csquotes
Installation instructions are given in the README files of all of
these
packages.
