Entities not spawning

[Xardov]

I'm trying to get a custom entity to spawn but it's not showing up at all.

 

http://pastebin.com/8uKFxqVY - BaseMod - I've registered the entity according to this tutorial:

http://pastebin.com/f5LA5Khf - CommonProxy - Nothing here really

http://pastebin.com/gSCre6wj - ClientProxy (maybe something to do with using RenderLiving instead of RenderBiped?)

http://pastebin.com/CfkXXiDP - EntityUndeadKnight

http://pastebin.com/zBg2QZvz - ModelUndeadKnight - really just a zombie model with the left hand down

 

I really have no idea what's causing this, as I've checked every tutorial I can find...

 

EDIT:  When I run start_client.bat it doesn't crash or anything.  The entities simply don't show up. 

'NOTHER EDIT: Also I didn't mess up any of the base classes so that's not the problem.
