Sure thing, but it's really nothing more than what was mentioned above:
Assets/Photon Unity Networking/PlayMaker/Actions/PhotonNetworkSetRoomCustomProperty.cs(53,80): error CS0117: `PlayMakerPhotonProxy' does not contain a definition for `GetValueFromFsmVar'
That's not the first error, but that's one of them. The first that I tried to deal with was the same, but in another file and for the ApplyValueToFsmVar method. The problem seems to be that the PlayMakerPhotonProxy is either out of date or the code that's using it in the demo scene is. I linked above where I got the demo, but the other stuff is built-in now, so I can't imagine I'm out of date on that.
