HB,
The template files need to be in a "templates" directory under the main BeerSmith directory where you have your executable. They are used directly by the program to generate previews and prints. You don't import them.
Ideally you should have installed BeerSmith using the normal route, and then dropped the patched executable into your BeerSmith directory to replace the existing executable. This will maintain your settings, templates, help files, etc.
Cheers,
Brad
