OpenRail 2020.r3 - Topo Import Tool USGS Terrain not working

When I try to create a new terrain using the Topo Import Tool>USGS Terrain, I don't get anything.

- I have a coordinate system selected (and tried a 2D and 3D model)

- I create a shape and set a Feature Definition

- I selected the shape and then there is a quick progress bar, but then it disappears and switches the tool back to the Selection tool and there is no terrain created and the shape properties didn't change.

- The Message Center gives me this "Topo Import functionality is part of Technology Preview" 

Is this tool not ready to be used? The release information said it would be in software.

Also, I'm currently asking within our company about an Esri password so I haven't been able to try that yet.
