Google Maps Reverse Geocoding API problem

programming flash

I just stucked with Google Maps Reverse Geocoding API (http://code.google.com/intl/hu-HU/apis/maps/documentation/geocoding/#ReverseGeocoding)
I have geolocation in lat and lon coordinates, and want to request some address detail to the location, thats why I want to use Google Maps API.

My code is the following:


public function getaddress(lat:Number,lon:Number):void{
		//Google Maps reverse geocode			
		var getVars:URLVariables = new URLVariables();
		getVars.q = lat+","+lon;
		getVars.output = "xml";
		getVars.sensor = "false"
		getVars.key=googleMapsAPIKey
			
		var uloader:URLLoader=new URLLoader()
		uloader.addEventListener(Event.COMPLETE,gapicomplete)
		uloader.addEventListener(HTTPStatusEvent.HTTP_RESPONSE_STATUS,statushandler)
		var apireq:URLRequest=new URLRequest("http://maps.google.com/maps/geo")
		apireq.data = getVars;
		uloader.load(apireq)
}

In the response I get the following XML:

<kml xmlns="http://earth.google.com/kml/2.0"><Response>
  <name></name>
  <Status>
    <code>610</code>
    <request>geocode</request>
  </Status>
</Response></kml>

The 610 error means bad API key.

The strange thing that, if I write the request simply in a browser (using the same API key) I get normal response with data.

I use Flash CS4 and AIR. Any advice? Thanks in advance!
