When I try to compile the .tex-file, I get an error, telling me that the pdflatex.ini is missing in \tex\config\pdflatex.ini.
I went looking into the directory - and the file is there. But TeXWorks tells me:
This is pdfTeX, Version 3.1415926-1.40.11 (MiKTeX 2.9)
miktex-pdftex.exe: The memory dump file could not be found.
miktex-pdftex.exe: Data: pdflatex.fmt
I also looked for miktex-pdftex.exe, and I found it in the bin.
Problem is, somehow I didn't got a new logfile.
I would appreciate some help with this. Thanks!

\tex\config\pdflatex.iniis a curious location. There should exists two pdflatex.ini (with different contents). One inmiktex\configand the other (needed for the format generation) in\tex\latex\config. Try to build the pdflatex format in miktex settings. – Ulrike Fischer Mar 1 '11 at 11:54miktex\config. – MiKa Mar 1 '11 at 13:41
