Unity not playing game in editor

Hi, I recently game across a problem. Whenever I press the play button, unity sits there and takes forever to load the game. I have waited about 20 minutes and nothing has happened. Everything was working fine until I added these two scripts:

MenuScript.js:

 var isOnList: boolean;

MenuManager.js:

 #pragma strict
 
 var MenuList : GameObject[];
 var MenuID : int;
 var TotalMenus : int;
 var MenuActive : boolean;
 var ActiveMenus : int;
 
 function Start () {
     TotalMenus = UnityScript.Lang.Extensions.get_length(MenuList);
 }
 
 function Update () {
     while (MenuID < TotalMenus)
     {
         if (MenuList[MenuID].activeInHierarchy)
         {
             ActiveMenus = ActiveMenus + 1;
             if (!MenuList[MenuID].GetComponent(MenuScript).isOnList)
             {
                 MenuList[MenuID].GetComponent(MenuScript).isOnList = true;
             }
             MenuID = MenuID + 1;
         }
         else
         {
             if (!MenuList[MenuID].activeInHierarchy)
             {
                 if (MenuList[MenuID].GetComponent(MenuScript).isOnList)
                 {
                     ActiveMenus = ActiveMenus - 1;
                     MenuList[MenuID].GetComponent(MenuScript).isOnList = false;
                     MenuID = MenuID + 1;
                 }
             }
             else
             {
                 MenuID = MenuID + 1;
             }
         }
     }
     if (ActiveMenus != 0 && !MenuActive)
     {
         MenuActive = true;
     }
     if (ActiveMenus == 0 && MenuActive)
     {
         MenuActive = false;
     }
     if (PlayerPrefs.GetInt("MenuActive") != 1 && MenuActive)
     {
         PlayerPrefs.SetInt("MenuActive", 1);
     }
     if (PlayerPrefs.GetInt("MenuActive") != 0 && !MenuActive)
     {
         PlayerPrefs.SetInt("MenuActive", 0);
     }
 }

This is very annoying and I want to get a new build of my game out by March 15th, 2016. Thank you in advance.
