I went to :
http://www.ftdichip.com/Drivers/CDM/CDM%202.04.06.exe (Calums original link, also the one in your post), and it said that it wasn't avaiable. So I tried going to the Driver section of the website, and there were 2 choices. I knew we had to use the one which creates 2 virtual ports, so the VCP was probably it.
In the list that you'll see, you can download 4 diff. versions for Windows (original and bug-fix, and both for 32k and 64k). Also in the last box, it says you can download an executable.
