Issues with disabling a component

I don’t know why but i can’t disable a unity component. Can someone help me?
In the console it says: The type or namespace name `MouseOrbit’ could not be found. Are you missing an assembly reference?

Scripts:
C# the one from i wish to disable the oter component:

    using System.Collections;
    using System.Collections.Generic;
    using UnityEngine;
    using UnityEngine.UI;
    
    public class GameEnd : MonoBehaviour {
    	
    	public GameObject Camera;
    	public Text StarsTxt;
    	public GameObject CanvasIG;
    	public GameObject CanvasEnd;
    	public int Stars;
    	// Use this for initialization
    	void Start () {
    
    	}
    	
    	// Update is called once per frame
    	void Update () {
    
    	}
    	void OnTriggerEnter(Collider EndPad)
    	{
    		if (EndPad.gameObject.tag == "Player") {
    
    			CanvasIG.SetActive (false);
    			CanvasEnd.SetActive (true);
    
    			Camera.GetComponent<MouseOrbit>.SetActive(false)();
    
    
    			GameObject Arena = GameObject.Find("Arena");
    			DeadCheck DeadCheck = Arena.GetComponent<DeadCheck> ();
    			Debug.Log (DeadCheck.accesableTime);
    			Debug.Log (DeadCheck.Deaths);
    
    			if (DeadCheck.Deaths <= 18 && DeadCheck.accesableTime <= 3) {
    				Stars = 3;
    				StarsTxt.text = "3";
    			} else if (DeadCheck.Deaths <= 30 && DeadCheck.accesableTime <= 6) {
    				Stars = 2;
    				StarsTxt.text = "2";
    			} else if (DeadCheck.Deaths >= 31 && DeadCheck.accesableTime >= 7) {
    				Stars = 1;
    				StarsTxt.text = "1";
    			}
    
    		}
    		//SaveProgress ();
    	}
    }

JS the script i wish to disable:

#pragma strict

var target : Transform;
var distance = 10.0;
 
var xSpeed = 250.0;
var ySpeed = 120.0;
 
var yMinLimit = -20;
var yMaxLimit = 80;
 
var distanceMin = 3;
var distanceMax = 15;
 
private var x = 0.0;
private var y = 0.0;
 
 
@script AddComponentMenu("Camera-Control/Mouse Orbit")
 
function Start () {
    var angles = transform.eulerAngles;
    x = angles.y;
    y = angles.x;
 
	// Make the rigid body not change rotation
   	if (GetComponent.<Rigidbody>())
		GetComponent.<Rigidbody>().freezeRotation = true;
}
 
function LateUpdate () {
    if (target) {
        x += Input.GetAxis("Mouse X") * xSpeed * distance* 0.02;
        y -= Input.GetAxis("Mouse Y") * ySpeed * 0.02;
 
 		y = ClampAngle(y, yMinLimit, yMaxLimit);
 
		var rotation = Quaternion.Euler(y, x, 0);
 
		distance = Mathf.Clamp(distance - Input.GetAxis("Mouse ScrollWheel")*5, distanceMin, distanceMax);
 
		var hit : RaycastHit;
		if (Physics.Linecast (target.position, transform.position, hit)) {
				distance -=  hit.distance;
		}
 
        var position = rotation * Vector3(0.0, 0.0, -distance) + target.position;
 
        transform.rotation = rotation;
        transform.position = position;
 
	}
 
}
 
 
static function ClampAngle (angle : float, min : float, max : float) {
	if (angle < -360)
		angle += 360;
	if (angle > 360)
		angle -= 360;
	return Mathf.Clamp (angle, min, max);
}

Thank you in advanced

If you want to disable a component of a different language, then you have to put that component to Standard Assets or Plugins folder. In your case, put JS script there.

Also, do not name your variables beginning with the capitalized letter. It is super confusing and it looks like you are trying to use statics. Especially this line DeadCheck DeadCheck = Arena.GetComponent<DeadCheck> ();. I believe even your compiler would get confused.
