I'm having issues creating a Hydro Network under the Network Tools (Using ArcMap 10.0).  I have a Drainage Line, Catchment Polygons, and Drainage Points, but struggling to accomplish the Terrain morphology steps. 

I performed all the Terrain preprocessing steps successfully.
In the Terrain Morphology, I  receive an error when creating Drainage Boundary Definition. 

Not sure what this error message means and how to correct it??
Thanks for the help
