[Dx4win] Import Filter question

[Scott Neader KA9FOX]

I want to tweak one of the provided Import Filters.  Namely, I want to use 
the N6TR2 filter, which imports native TR-Log files without RST, but I want 
to include the State field.

First, I can use the built-in N6TR2 import facility -- works great, it just 
doesn't import the State.

If I go to File > Import, choose N6TR2, use the "copy" feature, then try to 
use this copied filter without even changing anything... it errors out with 
"Error executing N6TR2"

To restate, if I take a working filter, and simply copy it, the copy can't 
import.  What am I doing wrong?
