Mecanim: 2D Blend Trees, Unable to Compute Positions.

I'm having trouble getting my animation I created in Blender to automatically to compute the positions with the animations provided. The model is a generic rig.

I was following the Unity:Stealth tutorial and upon the enemy set-up, it walks you through the setting up of the animation controller. However, while trying to set up my enemy following this video: http://unity3d.com/learn/tutorials/projects/stealth/enemy-animator-controller ,for some reason, I can't seem to get any of the animations to compute.

Here is the model and the simple animations as well. Can someone let me know if they can get any of these to computer positions, and how? : https://www.mediafire.com/?9eahboyw2yzybmd

I suspect it has something to do with the root motion.
