Hello every body,

When I write
HF:HNO$_3$:H$_2$O
15:1:2,5
I get
HF :HNO3 :H20

Chapter I

Meanwhile I updated MikeTex, Biber and Texniccenter yesterday.

With Texniccenter:
I can compile a first time (with pdflatex) but not ...

Thank you very much Johannes_B und Thorsten for your answers.
_ Johannes_B: I already have Latex Biber. I use it only when I want to compile over some chapters which have their own bibliographies.
_ Thorsten: Indeed. Since I suppressed the alpha-fr style, there is no failure anymore.
Thanks once ...
