How to Save Word Conversion Settings

I'm importing Word 2003 files into Robohelp 8 HTML.  The conversion is going well, but I cannot save the Conversion Settings.  Here's the steps I'm using:

1. Click File, Import, Word Document
2. Select a Word Document
3. In the Import window, click the "Edit" button (under Word Document, Edit Conversion Settings for Word Documents). 
   1. RoboHelp then scans my Word file for all styles and displays the Conversion Settings window.
   2. Map styles to Robohelp styles and select Pagination for all heading levels.
   3. Click OK, which returns me to the Import window.
4. In the Import Window, the Export... button is ghosted.  From here I want to save my Conversion Setttings so I can reuse them on other Word documents.

What am I missing?

Thanks,

Ron
