I don't know what this silly game is checking for...
Maybe there's a prob with the installed DirectShow-Filters.
DD installs one named 'ddsource.ax'.
You can temporaily uninstall it in this way:
Take a look to the file 'ddreg.bat'. Copy this file to a one called 'ddreg_u.bat'.
Uncomment the first line (delete the word rem) and comment the second line with an 'rem '.
Run 'ddreg_u.bat' - the filter should be deleted from system.
Try running your game...
To register again, simply run 'ddreg.bat'
