Trouble with Flash and Google Maps

Can someone please help me. I am in the process of building a Flash application the utilizes the Google Map APi. I have downloaded the following code:

import com.google.maps.LatLng;
import com.google.maps.Map;
import com.google.maps.MapEvent;
import com.google.maps.MapType;
import com.google.maps.InfoWindowOptions;
import com.google.maps.LatLngBounds;
import com.google.maps.MapMoveEvent;
import com.google.maps.overlays.Marker;
import com.google.maps.overlays.MarkerOptions;
import com.google.maps.interfaces.IPolyline;
import com.google.maps.services.*;

var dir:Directions;
var polyline:IPolyline;
var map:Map;
function setupMap()
{
      map = new Map();
      map.key ="ABQIAAAAjf2cvxDuc5J1E9CrJXmy9RQrAB2acdB4QgEQtVMeGDLCPkNwtRR8XAwx0MS9MI4RYmgwJ-jCIN9QaQ";
      map.setSize(new Point(400,400));
      map.x = 0;
      map.y = 0;
      map.addEventListener(MapEvent.MAP_READY, onMapReady);
      this.addChild(map);
}
setupMap();

function onMapReady(event:Event):void
{
      dir = new Directions();
      dir.addEventListener(DirectionsEvent.DIRECTIONS_SUCCESS,onDirectionsLoaded);
      dir.load("645 Carlton Road, Markham, ON to Fawnbrook Circle, Markham, ON");
}
function onDirectionsLoaded(event:DirectionsEvent):void
{
      var returnedDirection:Directions = event.directions;

      var startLatLng:LatLng = returnedDirection.getRoute(0).getStep(0).latLng;
      var endLatLng:LatLng = returnedDirection.getRoute(returnedDirection.numRoutes - 1).endLatLng;

      polyline = returnedDirection.createPolyline();

      // Remove everything from map and add back the markers and polyline
      map.clearOverlays();
      map.addOverlay(polyline);
      map.addOverlay(new Marker(startLatLng));
      map.addOverlay(new Marker(endLatLng));
      map.setCenter(returnedDirection.bounds.getCenter(), map.getBoundsZoomLevel(returnedDirection.bounds));
}

I am unable to generate a map but Iam getting the following error:

Line 36 1118: Implicit coercion of a value with static type com.google.maps.interfaces: IDirections to a possibly unrelated type com.google.maps.services: Directions

Can anyone help me with this issue?
