Has problem with Plugin in Unity 5!

I have installed unity 5 today, I add PUN+ plugin as usual, it has upgrate message!
It still work with my android device but when i switch to WP8 it has some troubles!
It has 2 files Photon3Unity3D, one in Assets/Plugins and the other in Assets/Plugins/WP8.

[1]
I uncheck all platform in file Photon3Unity3D at Photon3Unity3D int Assets/Plugins
and check WP8 in Photon3Unity3D at Assets/Plugins/WP8.
And it comes up with this error:

Assets/Plugins/ChatApi/ChatClient.cs(32,31): error CS0246: The type or namespace name `IPhotonPeerListener' could not be found. Are you missing a using directive or an assembly reference?
Assets/Plugins/ChatApi/ChatPeer.cs(15,31): error CS0246: The type or namespace name `PhotonPeer' could not be found. Are you missing a using directive or an assembly reference?


[2] I check Editor in file Photon3Unity3D at Photon3Unity3D int Assets/Plugins
and check WP8 in Photon3Unity3D at Assets/Plugins/WP8.
These errors are gone but it shows again when i build to WP8 project! (Exactly the same)

[3] I check WP 8 in file Photon3Unity3D at Photon3Unity3D int Assets/Plugins
and uncheck in Photon3Unity3D at Assets/Plugins/WP8.
All these error are gone and build has successfully!
But when i run the game on the WP8 device, it stop at the "PeerCreated" state!

Any one use PUN in Unity 5?
