VRTK failing to load vive model

I was trying to mess around with some VR stuff and at first, I could get Unity to recognize my Vive controllers. After uninstalling Unity and installing 2017.3.0f3, it finally recognized the controllers. Now in the editor window, I see the controllers moving around with the VRTK logo on them, but no model. The example teleport scene doesn't even show the controllers. The teleport beam goes from my invisible controller, to my feet. I get this in the console, but can't find a fix anywhere.



VRTK v.3.3.0
Steamvr Plugin v.1.2.3
Unity v.2017.3.0f3
