Server High Scores - crossdomain.xml

Hi, I am having issues getting unity webplayer to post high scores. I keep getting an error issue:

There was an error getting the high score: Rejected because no crossdomain.xml policy file was found UnityEngine.MonoBehaviour:print(Object) $:MoveNext() (at Assets/Scripts/HSController.js:32)

My game is uploaded here: http://dakar.bournemouth.ac.uk/~hmonaghan/unity/WebPlayer.html

And this is the script I'm using for the HSController.js file:

 private var secretKey="nottellingyou"; // Edit this value and make sure it's the same as the one stored on the server
     
 var addScoreUrl="http://dakar.bournemouth.ac.uk/~hmonaghan/unity/addscore.php?";
 var highscoreUrl="http://dakar.bournemouth.ac.uk/~hmonaghan/unity/display.php";    
 
 function Start() {
     getScores();
 }   
 
 function postScore(name:String, score:int) {
     //This connects to a server side php script that will add the name and score to a MySQL DB.
 
     // Supply it with a string representing the players name and the players score.
     var hash=Md5.Md5Sum(name + score + secretKey);
     var highscore_url = addScoreUrl + "name=" + WWW.EscapeURL(name) + "&score=" + score + "&hash=" + hash;
 
     // Post the URL to the site and create a download object to get the result.
     hs_post = WWW(highscore_url);
     yield hs_post; // Wait until the download is done
     if(hs_post.error) {
         print("There was an error posting the high score: " + hs_post.error);
     }
 }
 
 // Get the scores from the MySQL DB to display in a GUIText.
 function getScores() {
     gameObject.guiText.text = "Loading Scores";
     hs_get = WWW(highscoreUrl);
     yield hs_get;
     if(hs_get.error) {
         print("There was an error getting the high score: " + hs_get.error);
     } else {
         gameObject.guiText.text = hs_get.text; // this is a GUIText that will display the scores in game.
     }
 }

Can someone please help me?
