C# WWW texture and webplayer

I have a JS code that works when I used it in winwebplayer

 function setupTexture(){
 
     var mats = GetComponent.<Renderer>().materials;
     var clientPath : String;
 
     if(Application.platform == RuntimePlatform.WindowsWebPlayer){
         clientPath = Application.dataPath;
     } else {
         clientPath = "file://" + Application.dataPath;
     }
 
     var Skin : WWW = new WWW (clientPath  + "/TextureArray/01Skin/test.png");
     var Feet : WWW = new WWW (clientPath  + "/TextureArray/02Shoes/test.png");
     var Legs : WWW = new WWW (clientPath  + "/TextureArray/03Pants/test.png");
 
     yield Skin;
     yield Feet;
     yield Legs;
 
     mats[0].mainTexture = Skin.texture;
     mats[1].mainTexture = Feet.texture;
     mats[2].mainTexture = Legs.texture;
     mats[2].color = new Color(Random.Range(0f,1f) ,Random.Range(0f,1f),Random.Range(0f,1f),1f);
 
     GetComponent.<Renderer>().materials = mats;
 
 }

I have tried to convert it to C# but I can not get it to work in the webplayer

 //    private IEnumerator setupTexture(){
     private void setupTexture(){
 
         Material[]     mats = this.gameObject.GetComponent<Renderer>().materials;
         string         clientPath;
 
         if(Application.platform == RuntimePlatform.WindowsWebPlayer){
             clientPath = Application.dataPath;
         } else {
             clientPath = "file://" + Application.dataPath;
         }
 
         WWW Skin = new WWW (clientPath  + "/TextureArray/01Skin/test.png");
         WWW Feet = new WWW (clientPath  + "/TextureArray/02Shoes/test.png");
         WWW Legs = new WWW (clientPath  + "/TextureArray/03Pants/test.png");
 
 //        yield return Skin;
 //        yield return Feet;
 //        yield return Legs;
 
         mats[0].mainTexture = Skin.texture;
         mats[1].mainTexture = Feet.texture;
         mats[2].mainTexture = Legs.texture;
         mats[2].color = new Color(Random.Range(0f,1f) ,Random.Range(0f,1f),Random.Range(0f,1f),1f);
 
         this.gameObject.GetComponent<Renderer>().materials = mats;
     }

I tried with and w/o the yield in c#. As is, it works in the editor and in a winClient Anyone that can point me in the direction of what I am doing wrong in relation to the webclient.

[EDIT] >> The code loads 3 png files and put them onto model. when I use the C# version in the webplayer no textures are loaded but no error about unfound paths are shown either. when run' from a winexeclient the textures are loaded. [EDIT] <<

Note. I do not fully understand what yield does so it might be that I use it wrong?
