Error: by can't contain join column LINEARID which is missing from LHS #3
Description
I was able to run the Worldwide version, which is very cool, but the only road detection I am seeing on the map is the interstates:
So, I am attempting to run the UnitedStates version (after downloading all the necessary feature names and road files) and I am running into the following error:

I have the FeatNames and Roads folder in the same path as the UnitedStates file:
