Re-loaded Wow onto Widnows machine

I've just loaded WoW onto my Widnows machine as my Mac needs to be wiped clean and re-partioned.

The download after the installation took me nearly all day. And now I find I can't load the subsequent installments of:

The burning Crusade
Wrath of the Lich King

Is it possible that they were included in the massive download of yesterday? Is there any way I can check if they are loaded?
