You do not substitute the template for your Normal.dotm. [EVER]
Double-click on the supplied template. Or, use File > New and pick the template if it is properly stored. This should create a new document based on the supplied template.
All of your macros stored in your
Normal Template will still be available.
Styles will not. Keyboard shortcuts will. Building Blocks including AutoText will be available. Formatted AutoCorrect will be available.
Thank you for the homage. I apologize if my article is unclear.
