VBA thoughts
This would be properly addressed in the vba forum but has nothing to do with your question. It does have to do with your template.

The macro in ThisDocument AutoNew should likely be a Document_New procedure instead.

I'm not sure why you are using a userform to get a folder and document name. You are reinventing the wheel. In my opinion, it is very intrusive to workflow. You could be simply using the SaveAs dialog. However, simply creating a new document will mean that your user will need to choose a folder and path without doing anything. If you want help with these points, do ask in the vba forum.
