Elk is Great! but I just can't make a topography!exactly

elk is a great tool! I use it a lot with osm files.

but I can't make the topography to work. I installed the latest version (2.2.2) on grasshopper 0.9.0076.

no matter what I connect and how it shows that there is no Information in points, curves and surface output. 

also I tried different files and location.

can someone help me please?
