Character not animating

Hi there. Recently downloaded a model over at http://www.dexsoft-games.com and imported it into my game. I've got movement down, but for some reason the character won't animate when calling something like "animation.CrossFade("jump");"

The weird thing is, the character moves as if it's animated, like bouncing back and forth at idle, but the actual model stays rigid. I have a character controller on it, set all of the animations the model has under "Animation", and set the appropriate frames for all of its animations. What's going on?
