No hair for Big Buck Bunny in 2.61

I am having an issue with the project files for Big Buck Bunny in 2.61. The hair is not rendering or even active in the 3D view. Anyone else have this problem or a suggestion on how to fix it?

Wasn’t Big Buck Bunny made in 2.4x version of Blender? Not all of the previous version model is not fully compatible to 1.61 I think.
