Fine Volume mesh makes NetGen.exe closing

 
Hi,

I have a simple example on a .geo file where the volume meshing is working with ver. 5.3.
It is not working with ver.  6.2.2301 when meshing is defined as  "Fine" or "Very Fine".
The software simply close without any further message.
I have worked worked with different boundingboxes without succes.

Can someone explain it?

PS I cannot attach the geo file. There seems to be an error in the browser.
So here it comes:
