Problems with Animator

I am having problems with the animator which is preventing me from continuing on, the problems are...
Assets/Photon Unity Networking/Editor/PhotonNetwork/Views/PhotonAnimatorViewEditor.cs(62,32): error CS1061: Type `Animator' does not contain a definition for `layerCount' and no extension method `layerCount' of type `Animator' could be found (are you missing a using directive or an assembly reference?)

Assets/Photon Unity Networking/Editor/PhotonNetwork/Views/PhotonAnimatorViewEditor.cs(90,48): error CS1502: The best overloaded method match for `UnityEditorInternal.AnimatorController.GetEffectiveAnimatorController(UnityEngine.Animator)' has some invalid arguments

and

Assets/Photon Unity Networking/Editor/PhotonNetwork/Views/PhotonAnimatorViewEditor.cs(90,48): error CS1503: Argument `#1' cannot convert `Animator' expression to type `UnityEngine.Animator'

I am new to this stuff but I know that something is not working please fix, I don't even now if I am asking this in the right place
