600's post just helped me figure this out.
I downloaded the package straight from the site, but my Photun Unity Network Folder does NOT have a Playmaker folder inside of it. It has the DemoWorker-Scene and DemoWorkerGame-Scene, but that's not what I needed.
HOWEVER, the scene I AM looking for (with functioning FSMs!) is located in Assets >Playmaker Custom Samples >PhotonUnityNetwork > DemoWorker.
I have no idea why it would be put in a different spot like that, but I'm able to see it now. So consider me grateful and confused!
