Problem with events

Hello, I have a problem where I've set up a simple event when google authenticates, like so:

public class GoogleStuff : MonoBehaviour {

 public delegate void GoogleLogin();
 public static event GoogleLogin OnGoogleLogin;

 void OnEnable (){
     PlayGamesPlatform.Activate();
     PlayGamesPlatform.DebugLogEnabled = true;
 }

 void Awake () {
     Social.Active.localUser.Authenticate ((bool success) => {
         if(success){
             Debug.Log("Authetication Success");
         } else {
             Debug.Log("Authetication Failed");
         }
     });
     if(OnGoogleLogin != null){
         print ("firing event");
         OnGoogleLogin();
     }
 }

}

and I've subscribed an to the event with:

 void OnEnable (){
     GoogleStuff.OnGoogleLogin += ActivatePlayer;
 }

 void ActivatePlayer (){
     print ("Event recieved");
     UserName = Social.Active.localUser.userName;
     LoadPlayerData ();
 }

The ActivatePlayer function is not being called even though I'm getting the "fired event" log from the login. I assume I've done something wrong but I can't seem to find the right answer. Thanks for all the help.
