Dungeon Keeper 2 ~ update help

[Causmo Quee]

I d/l DK2 a few days ago from Kazaa. I heard it was a pretty nice game so I thought I'd check it out.

anyway...I tried updating to ver. 1.7 but it wont work. I get an error message saying:

"You must first install DK2 before the update can be applied."

So my question is how do I apply the update?

Thanks =)
