Thanks for the quick response!!
I guess it only shows up there if you purchased it in the past... I don't see it. I've looked all over the Stardock site, including a few links to purchase it, that 404.
I tried a DL from I think download.cnet.com, but it crashes when I try to change the theme. (And, it's the public version, so I can only use the supplied Mac and Vista themes..)
