There is a problem because you changed the default name of the VTKData 
repository :) If you downloaded the data from either vtk40Data.zip or 
vtk40Data.tar.gz, etc., all data files come within a VTKData directory. VTK 
tries different directory to find its data. It it does not find one, it 
defaults to ..\..\..\..\VTKData. There is no way to guess that you chose 
vtk40data :)

BUT, the safe and usual way to avoid that problem is very simple, just set 
your VTK_DATA_ROOT environment variable to the path where you data are 
(here, D:/vtk40data).

Hope this helps
