Timescale wont work

Everything was working perfectly until yesterday. I dont know what happened but all of my timescales stopped working (I cant set the timescale to 0 if i want to pause my game)and i cant make it work with my pause script. Anyone know the problem? Im using ui for the pause script.Heres my pause script.

             public bool paused = false;
     public GameObject pause; // Assign in inspector
     private bool isShowing;
     bool restart;
     bool shop;
     bool menu;

     void Start ()
     {
             pause.SetActive(false);
             paused = false;
             Time.timeScale = 1;
     }

     public void Pause (bool paused)
     {
             pause.SetActive (true);
             Time.timeScale = 0;
     }

     public void UnPause (bool paused)
     {
             Time.timeScale = 1;
             pause.SetActive (false);
     }

     public void Restart (bool restart)
     {
             Application.LoadLevel ("main");
     }

     public void ShopLevel (bool shop)
     {
             Application.LoadLevel ("shop");
     }

     public void Menu (bool menu)
     {
             Application.LoadLevel ("-main menu");
     }
