FLASH: TypeError: Error #1010 when calling a class (Flash 9 - AS3)

First of all, hello all, this is my 1st post here, so I’d like to take the opportunity to greet you all.

Now,
I got this class desat.menus.HorizontalMenu
I want to make an instance of this class in a fla-file, but I get the following runtime error:


TypeError: Error #1010: A term is undefined and has no properties.
    at desat.menus::HorizontalMenu$iinit()
    at fcms_fla::MainTimeline/fcms_fla::frame1()

The forum search nor google gave me a solution for this.

This is my code

FLA-file


import desat.menus.HorizontalMenu;
var arr:Array = new Array();
arr.push("home");
arr.push("news");
var $root:MovieClip = this;
var menu:HorizontalMenu = new HorizontalMenu($root, arr, 10, 10 ,120);

HorizontalMenu.as (inside /desat/menus/ )

}

Any experiences or help with this would be greatly appreciated, as I’m really stuck here.

Edit: I narrowed down the problem and found it is somewhere inside the for-block.
