Thanks a lot, it works now!!

I will just leave this here for all your pre-loaded texture issues:

 

@EventHandler
public void postInit(FMLPostInitializationEvent event) {
   /** TODO Hack to get our textures for items and blocks to show, remove when the bug is
     * fixed in an update.  If this is not done, then the player must manually refresh
     * the texture packs. */
   if (event.getSide() == Side.CLIENT)
      Minecraft.getMinecraft().refreshResources();
}

 

Edit: As pointed out in the post below this is a bad practice and you are supposed to register it all in the pre-init event.

Initialize and register in the FMLPreInit event, no sooner nor later.
