Using Word templates

Hi,

I want to export my Robohelp 7 HTML help to a Word document. I want the output to look exactly like the main help file, but want to add some headers and footers using a Word template,

Here's what I've tried:
In the Single Source Layouts> Printed Documentation.
In the Print Document Appearance step of the dialog.
Using the Microsoft Word Template drop-down options:

When I select 'Use the Project's CSS styles' the topics come out looking just as I want it, but as it's not using a Word template there are no headers or footers.
When I select any attempt at a Word template I've created, it just seems to ignore it and go with the styles on Style Mapping.dot.
When I try to edit Style Mapping.dot, it seems to ignore any changes I make and goes back to the default.

Any advice on how to creat a template that will work, or how to turn my Robohelp CSS into a template that will work, much appreciated.

Thanks

Simon
