Extremely simply preloader problem... doing my head in!

So simple you wouldn’t believe, but it just refuses to work, here’s my code:

package {
    import flash.display.*;
    import flash.net.*;
    public class Gameloader extends MovieClip{
        public function Gameloader() { 
            var request:URLRequest = new URLRequest("Elf_game.swf");
            var loader:Loader = new Loader();

The above code is the main document class of my loader file, there’s absolutely nothing else to the file at all.

I get the following errors:
1061: Call to a possibly undefined method load through a reference with static type Loader.
1067: Implicit coercion of a value of type Loader to an unrelated type flash.display:DisplayObject.

I just don’t get it, I’m obviously doing something wrong.

Please help me!!
