If this was asked before, I apologize, I searched for it but did not find it anywhere.

I just bought Civilization IV Gold a couple days ago and am trying to get the complete manual off of disk three, like the packaging says. Unfortunately I am so far unable to do so, all that is on disk 3 is a cab file. The abridged manual makes me feel like I am missing some good info considering it mentions nothing of warlords.

Has anyone had this problem, and if so, have a fix for it?

The manual is out of date and useless, you aren't missing anything.
