Bug Blender FBX export won't play animations in Unity.

Hello! I'm using wow models to help me with learning how to make animations with rigs, and I've noticed something odd. Whenever I try and export this model of a Tauren with Blender into an FBX file, animations won't play on it. However if I use the FBX file of the tauren from WMV and insert it into Unity, the animation works. So I came to the conclusion that it must be FBX export settings that's bugging the rig or the animations. On the left you see the WMV raw FBX, and on the right you see the FBX I exported from Blender. I'm curious if a professional can help point me to the right direction by giving me some export settings I can toy around with.
