If you got the 'Nie mozna otworzyc pliku avi' 
error with the release of Mortyr that was posted 
here, unzip these files in the Mortyr directory,
where mortyr.exe resides.  Run plikufix.exe to play
the game. If you got no sound, run 'plikufix.exe setup'
and enable sound as well as other options.

This plikufix.exe is the same file as in archive mortyr3.zip
found on the web site.  CD check has been disabled as well as
data version check for one can play the full game with it!
