Movement doesnt work if I rotate my model

Hi!

I am having some troubles with my movement script. If I test it with a normal cylinder and a character controller mesh it works fine. The problem is, when I import my model to the scene, it changes the axis or something like that.

If I import and select all rotate values to 0 (as image): it works (of course the character is lied) http://img820.imageshack.us/img820/4668/sinrotaar.jpg

If I try to rotate the character in the position I want: http://img839.imageshack.us/img839/1065/sinrotar.jpg

It doesnt work. I think is something related to the axis, cos I only can Jump.

I add my movement script maybe I'm doing something wrong (I know my code is not the best, but I'm still starting and I have to learn a lot).

 function Update () {
 var controller : CharacterController = GetComponent(CharacterController);        
 var right : Vector3 = transform.right * speed * Input.GetAxis("Horizontal");
 var forward : Vector3 = transform.forward * speed * Input.GetAxis("Vertical");
 
     
 right.y = moveDirection.y; // keep current vertical velocity
 right.z = forward.z;  // z z
 moveDirection = right; // but update horizontal velocity
 
 //Doble salto
 if (controller.isGrounded) {  //If the player is on the floor
     contadorsalto = 0;             //Reset the counter
     moveDirection.y = 0;
     if (Input.GetButtonDown ("Jump")) {  //When press space
         moveDirection.y = jumpSpeed;  //Jump
         contadorsalto = 1;             //Counter = 1
     }
 } else {                            //If the player is NOT on the floor
     if (contadorsalto < 2) {        // and the counter is less than 2 (only 1 jump)
         if (Input.GetButtonDown ("Jump")){  //When we press space
             moveDirection.y = jumpSpeed;  //Jump
             contadorsalto = 2;                //Counter = 2 so it won't enter again until player is in the floor 
         }
     }
 }

 moveDirection.y -= gravity * Time.deltaTime;

 controller.Move(moveDirection * Time.deltaTime);
 

}

Thanks in advance!
