OSSmooth not working

Hi,
 
I created a lattice optimized structure, and I would like to export it to an *.stl file, but first I would need to run OSSmooth on it.
 
When I try to do so, HyperMesh says:
'Invalid input file command. Please check logfile'
I checked the logfile, where I found:
'Warning: failed to detect topology optimization result, turn off isosurface
Error: OSSmooth fail to detect optimization result. Abort.'
I turned off isosurface, but there is another error:
'Invalid parameters string'
 
No matter what I change in the settings of OSSmooth panel, I can't make it work.

I attach the files as *txt, rename it to *.rar

Thank you

Zsombi
