[CLOSED] Starting multiplayer/networking difficulties - not updating host

Hey all, jumping into multiplayer for the first time! I've been running through two resources in parallel:
1) http://docs.unity3d.com/Manual/UNetConverting.html
2) https://www.youtube.com/watch?t=49&v=NLnzlwCRjgc

I'm at 10:40 in the youtube tutorial where we've added the NetworkManager object with NetworkManager and NetworkManagerHUD components, added the player prefab, and the NetworkIdentity and NetworkTransform components to the player prefab. According to the vid, at this point I'm able to launch two copies of the game and see them interact, but my editor copy (host) works fine while my .exe copy (client) doesn't affect the game scene in Unity (or the host game). I've ran through the vid a number of times and I've copied them verbatum regarding the network pieces, although I am using my own game rather than a fresh one. Ideas on what I'm missing? I'll attach some images from my project:

 

Didn't see there's a forum specific to multiplayer. I'll mark this one as closed and move it over there where it belongs.
