FindObjects" method quits working....

Ok, so I have worked my way through the FSM tutorial and the Airplane tutorial and I am trying my own attempt at a hybrid of the two and here is my issue:

From the FSM tutorial, I modified the _GetUnit method like so:

protected List<ISceneContainerObject> _GetUnit(Vector2 location, TorqueObjectType unitType)
        {
            List<ISceneContainerObject> foundObjects = new List<ISceneContainerObject>();
            T2DSceneGraph mySceneGraph = (T2DSceneGraph)TorqueObjectDatabase.Instance.FindObject("DefaultSceneGraph");

            mySceneGraph.FindObjects(location, 1.0f, unitType, 0xFFFFFFFF, foundObjects);


            if (foundObjects.Count > 0)
            {            
                return foundObjects;
            }
            else
                return null;
        }

This is working great UNTIL, I decided to use this piece of code from the Airplane tutorial to mount a camera on my player:

protected void PlayerCamera(T2DSceneObject player)
        {
            //do playerCam
            T2DSceneCamera WorldCam = new T2DSceneCamera();
            WorldCam.CenterPosition = new Vector2(0.0f, 0.0f);
            WorldCam.Extent = new Vector2(100.0f, 75.0f);
            TorqueObjectDatabase.Instance.Register(WorldCam);
            TorqueObjectType playerCam = TorqueObjectDatabase.Instance.GetObjectType("playerCam");
            if (player != null)
            {
                WorldCam.Mount(player, "select", false);
            }

            // display the camera on screen
            GUIStyle WorldStyle = new GUIStyle();
            GUISceneview WorldView = new GUISceneview();
            WorldView.Style = WorldStyle;
            WorldView.Camera = WorldCam;
            WorldView.RenderMask = playerCam; // only render objects of type "playerCam"
            GUICanvas.Instance.SetContentControl(WorldView);

        }

Now, whenever I go to select my unit, I dont get anymore results??? If I comment out the PLayerCamera method, I get my results back. I am still VERY newb to all this so hopefully someone can help me out. Much thanks in advance.
