17th December 2003
Microsoft has stated that the file converter packs for all versions of Office prior to Office 2003 have been discontinued and are no longer available.
The Office 2003 converter pack does not list a WordStar filter!
However, the WordStar filter is still available seperately on Microsoft's ftp site. See the Conversion FAQ page on the WordStar Resource Site for the latest link: http://www.wordstar.org/wordstar/pages/convert_faq.htm#Q3
