Problem with Application.Loadedlevel

Hello everyone. I've got a problem with the "retry" button on my GUI: it reloads the scene, but the spawner I have in it does not work, and I can't understand why. The code I use in Unity 4.6 Beta to load the same level is

 function Reload () {
 Application.LoadLevel(Application.loadedLevel);
 }

and the code attached to my spawner is

 var enemy : GameObject;
 var spawnValues : Vector3;
 var hazardCount : int;
 var anglex : int;
 var angley : int;
 var anglez : int;
 var spawnWait : float;
 var startWait : float;
 var waveWait : float;
 var randomnumber : float;
 public var isSpawning :boolean = true;
 
 function Awake(){
     if (!isSpawning) {
     isSpawning=true;
     }
 }
 
 function Start () {
     if (isSpawning==true){
     SpawnWaves ();
     }
 }
 
 function SpawnWaves () {
     yield WaitForSeconds (startWait);
     while (true)
     {
         for ( var i : int= 0; i < hazardCount; i++)
         {
              var spawnPosition : Vector3= new Vector3 (Random.Range(-randomnumber,randomnumber), spawnValues.y, spawnValues.z);
              var spawnRotation : Quaternion= Quaternion.Euler(anglex, angley, anglez);
             Instantiate (enemy, spawnPosition, spawnRotation);
             yield WaitForSeconds (spawnWait);
         }
         yield WaitForSeconds (waveWait);
     }
 }

Any help would be very appreciated.

Thank you! :D
