Third Party Photon Network Instantiate Problem

I am making a multiplayer game and I have the code to connect to the server and join a room and all that. But when I try to do "PhotonNetwork.Instansiate("Seeker", Vector3.zero, Quaternion.identity, 0);" It just says failed to instantiate prefab "Seeker". It doesn't tell me why, just that it failed to do so. How do I fix this?

 

Please copy-paste full error message here.
I see at least 3 error messages in PhotonNetwork.Instantiate() method . All with failure descriptions.

 

Here is the error:

Failed to Instantiate prefab: Seeker. Client should be in a room. Current connectionStateDetailed: PeerCreated
UnityEngine.Debug:LogError(Object)
PhotonNetwork:Instantiate(String, Vector3, Quaternion, Int32, Object[]) (at Assets/Plugins/PhotonNetwork/PhotonNetwork.cs:2026)
PhotonNetwork:Instantiate(String, Vector3, Quaternion, Int32) (at Assets/Plugins/PhotonNetwork/PhotonNetwork.cs:2009)
OnGameStart:Start() (at Assets/My Resources/Scripts/Networking/OnGameStart.cs:6)

Here is the code:

using UnityEngine;
using System.Collections;

public class OnGameStart : MonoBehaviour {
void Start () {
PhotonNetwork.Instantiate ("Seeker", new Vector3(333.043f, 23.18f, 203.783f), Quaternion.identity, 0);
}
}

I was using javascript first but photon doesn't like javascript for some reason so I just used csharp.

 

The message states failure reason very clearly: "Client should be in a room. Current connectionStateDetailed: PeerCreated".
Join room first and move PhotonNetwork.Instantiate() call from Start() to OnJoinedRoom().

 

I did that but im still getting this error

PhotonNetwork.ConnectUsingSettings(Version + "." + SceneManagerHelper.ActiveSceneBuildIndex);
