aha, that was the problem all along. In your README file, it was adamant about only sending the ROUTE POINTS to the GPS emulator. But when I chose "ROUTE DIRECTIONS" instead of "ROUTE POINTS" it worked fine.

Your readme gives examples from a different version of StreetAtlas, I think. The menu options and stuff in SA USA 2K3 seem to be different from what your readme instructions expected to see.
