Can't find actor in asset browser (Motionbuilder PLE 7)

I'm following the guide at
http://atec.utdallas.edu/~midori/Handouts/motionBuilder_actor.htm and in step 2,
when it tells me to drag an actor in, I can't find the actor in my asset
browser.

I've searched around a bit, but haven't found anything about the actor not being
included in the Personal Learning Edition, so I looked it up in the help that
comes with PLE 7.  It says to create an actor, "Drag an Actor asset from
the Characters folder of the Asset browser into the scene."

The only things that show up on my asset browser are: "Actor Face,"
"Character," "Character Extension," and "Character
Face."  A screenshot of my asset browser is located here:

Is there anything specific I have to do to add the actor, or is it just not
included at all in the PLE?

Thanks for any help anyone can give me,
