Can not send RPC function since no connection was started?

Hello people, I keep getting the error: Can't send RPC function since no connection was started. Can't send RPC function since no connection was started. UnityEngine.NetworkView:RPC(String, RPCMode, Object[]) Loader:LoadLevel(String) (at Assets/Scripts/Main/Loader.cs:63) LoaderGui:Host(String) (at Assets/Scripts/Main/LoaderGui.cs:94) LoaderGui:ServerList(Int32) (at Assets/Scripts/Main/LoaderGui.cs:38) UnityEngine.GUI:CallWindowDelegate(WindowFunction, Int32, GUISkin, Int32, Single, Single, GUIStyle)

I get these errors when I try to start a server after downloading Counter Strike Port Source Code ( http://forum.unity3d.com/threads/103919-cs-port/page6 )

Here is the script:

     internal string playerName { get { return isEditor ? NickNameEditor : PlayerPrefs.GetString("PlayerName", "Guest" + Random.Range(0, 99)); } set { PlayerPrefs.SetString("PlayerName", value); } }
