Maybe CW sells only the Mod III and stops supporting the Mod II? Older versions of a good product they let fall down like a hot potato.
Sending the Mod-II-zip-file doesn't make very much sense, because the new user needs a registration key.
Creamware seems to be doing some kind of server update: When you click the link for the main software, you get redirected to version 3.1c, but the link doesn't work.
I think they'll fix it monday...
