SOLVED!!

Yesterday I used the Norton/Symantec removal tool to uninstall and remove Norton Internet Security 2006 from my machine. It also deleted/removed some of the MSXML4 files that Webstyle needs.

I went to:
http://www.microsoft.com/downloads/d...DisplayLang=en and downloaded/installed the MSXML4 files from there.

Now Webstyle and Xara X1 are working again.

Thanks for your time.
