[texhax] Error: File ´rerunfilecheck.sty´ not found.

[Schmitt Eberhard Dr.]

Sirs, 
for the past months I have worked satisfactorily with Miktex using
Latex==>PDF.
This morning the administrator updated the repositories. Now I cannot use
pdflatex anymore when using the beamerclass.(The article class still works). 
I keep receiving the following error information: Hyperref stopped early.
Latex Error: File ´rerunfilecheck.sty´  not found. 
In /C:\Programme\MiKTeX 2.7\tex\latex\oberdiek I find ´rerunfilecheck.sty´,
though! Why cannot the system find it?
I would not know how to use something like the command ´texhash´ (as is
recommended for Linux  systems) in WindowsXP.
I could not find any more help in the Internet.
Thank You very much in advance
Dr. Eberhard Schmitt
