Hi all!
i have problem with PlayerIO. When i connect to server, then i not see other players

PlayerIOClient.PlayerIO.Connect(
			"world-of-zukaro-2ucj4k7phewsufpcsff6ow",	// Game id (Get your own at playerio.com. 1: Create user, 2:Goto admin pannel, 3:Create game, 4: Copy game id inside the "")
			"public",						// The id of the connection, as given in the settings section of the admin panel. By default, a connection with id='public' is created on all games.
			userid,							// The id of the user connecting. This can be any string you like. For instance, it might be "fb10239" if youґre building a Facebook app and the user connecting has id 10239
			null,							// If the connection identified by the connection id only accepts authenticated requests, the auth value generated based on UserId is added here
			null,
			delegate(Client client) {
				Debug.Log("Successfully connected to Player.IO");

				//Create or join the room 
				client.Multiplayer.CreateJoinRoom(
					"Red Room",					//Room id. If set to null a random roomid is used
					"UnityMushrooms",						//The room type started on the server
					true,								//Should the room be visible in the lobby?
					null,
					null,
					delegate(Connection connection) {
						Debug.Log("Joined Room.");
						infomsg = "Joined Room.";
						// We successfully joined a room so set up the message handler
						pioconnection = connection;
						pioconnection.OnMessage += handlemessage;
						joinedroom = true;
						GameObject newplayer = GameObject.Instantiate(PlayerPrefab) as GameObject; 
						
					},
					delegate(PlayerIOError error)
