Witam.
Gdy probuje:
texexec cos.tex

Wyzuca mi blad o tresci:
 TeXExec 2.5 - ConTeXt / PRAGMA ADE 1997-2001

            executable : pdfetex
                format : cont-en
             inputfile : test2
                output : standard
             interface : en
          current mode : all
               TeX run : 1

This is pdfeTeX, Version 3.14159-13d-2.1 (Web2C 7.3.1)
Sorry, I can't find the format `cont-en.efmt'; will try `context.efmt'.
I can't find the format file `context.efmt'!

              run time : 0 seconds

Prosze o pomoc.
Pozdrawiam.
