Using Free North American Detailed Streets for Network Analysis

I'm not new to ArcGIS, but I am new to ArcGIS 10.

I've done service area analysis in the past, but this was done on a University computer maintained by IT.

I downloaded and installed the free trial software for both ArgGIS 10 and Network Analyst, and I downloaded the free "North American Detailed Streets for Network Analysis" layer package from here:

I added the streets to a basemap, activated the network analyst extension, and added the network analyst toolbar. But all options are 'grayed out' on the 'network analyst' dropdown window.

I suspect that I need to build a network from the streets layer package.

Has anyone else gone down this path?

Any guidance is greatly appreciated.
