Using FlxScrollingText

[JonnyTech]

Can anyone see what is wrong with the following code?

package;

import flixel.FlxState;
import flixel.addons.plugin.FlxScrollingText;
import flixel.text.FlxBitmapText;
import flash.geom.Rectangle;

class BlahBlah extends FlxState
{
    override public function create():Void
    {
        var scrolltext = new FlxBitmapText();
        var scroller = FlxScrollingText.add(scrolltext, new Rectangle(20, 20, 200, 40), 1, 0, "*TEST* ");
        add(scroller);
        super.create();
    }

    override public function update(elapsed:Float):Void
    {
        super.update(elapsed);
    }
}

These are my current versions:

I am compiling on Linux to neko but I get a static garbled output:

Similar results with html5 and flash - can anyone help? (Please bear with me as I am very new to haxe)
