Clinton, I unzipped it and viewed it in ArcCatalog and it doesn't appear to have a network dataset built? In order to build a network dataset you need to have all of the features which participate (save for tables) in a Feature Dataset, then right click - new - network dataset and follow the steps. If you have the network dataset built can you share the geodatabase with the network dataset.
