I've installed, and I go to my admin URL page, and log in. Following instructions I've found on various sites from googling, I try to find the "SYSTEM > CONFIGURATION" tab and there is no such thing.

I'm lost trying to find this, and as I mentioned everything I've found via google has an interface that looks completely different than what I see on our install.
Here are two links to show you what I'm talking about:
