Missing lip synch animation groups?

I'm attempting to lipsynch the Engineer. so far I have the engie and all my lights set, I have the audio in the timeline... but my engineer animation set doesn't have a lower face group.

What's up with that?

it's the tf2 stock Engineer.mdl if you think I screwed up

I posted this earlier but someone suggested a better title. Maybe someone can help me out here

EDIT: For those of you in my situation, you need to select the Engineer model from the HWM directory in TF2/Player. It works great now
