Has anyone gotten this player model to work?

I downloaded this player model, but it doesn’t seem to work.

I first made it its own addon folder with an info file, and the model showed on the player model selection list, but it would load as Dr. Kleiner. Then, I just put all of the files into the folders of the garrysmod folder, and the model showed once again on the player model selection, but it still Dr. Kleiner. Has anyone gotten this model to work?

If I go to the folder and load it as a ragdoll, it will load, but not as a player model.
