character doesn't move

Alright, I have a 3rd person character controller in the scene, a terrain, and a camera that is supposed to follow the main character?
However, when I press the WASD keys to make the character move, nothing happens?
This is the first time it has happened to me. When I tried it before, it worked fine!
What am I doing wrong?

We need to see your code, but, in order to move forward, your code should looks something like this:

var MoveDirection : Vector3 = Vector3.zero ;

MoveDirection = Vector3(Input.GetAxisRaw(“Horizontal”), 0, Input.GetAxisRaw(“Vertical”) );

MoveDirection = (transform.TransformDirection ( MoveDirection )*Controller.Player.Speed)*Time.deltaTime;

transform.position += MoveDirection ;

I’ve received three responses while I was out. I’m on a slow network.
I’m uploading two files, as a single file is too large for the upload!
BTW, I’m developing y project in Unity 3D 3.4.2

Here are the files. It may take some time!!
