        var aToken = Facebook.Unity.AccessToken.CurrentAccessToken;
        // Print current access token's User ID
        Debug.Log(aToken.UserId);

    }
}

 }

Find FacebookGameObject.cs .. then replace this:

public void OnInitComplete(string message)
        {
            this.Facebook.OnInitComplete(message);
            this.Initialized = true;        
        }

with this:

public void OnInitComplete(string message)
        {
            this.Initialized = true; 
            this.Facebook.OnInitComplete(message);          
        }

This mistake will be fixed in the next patch..
