Update problems

I just saw the new Update was available so I updated and followed your link to the manual changes and the update imported without problem and I did all the manual changes necessary. when I went to run my game this error appeared.

Assets\Opsive\UltimateCharacterController\Add-Ons\Multiplayer\PhotonPUN\Scripts\Character\PunCharacter.cs(26,60): error CS0535: 'PunCharacter' does not implement interface member 'INetworkCharacter.ItemReloadComplete(ItemAction, bool, bool)'

can you tell me why and how do I fix it? thanks
Okay I was just informed that the PUN Multiplayer also has an update so I updated it and it fixed my problem sorry I didn't look for that sooner my fault.
