Help Flex Problem

programming flash
1

Hi i have just downloaded Flex Builder 2 and Flash 9 player for Internet Explorer. I added this piece of code in my ProgrammingBasics.as file:


[LEFT] package {
	import flash.display.Sprite;

	public class ProgrammingBasics extends Sprite
	{
		public function ProgrammingBasics()
		{
			var quantity:Number = 9;
			trace(quantity);
		}
	}
}

However, when i clicked on the debug button i get this messag;

Failed to connect; session timed out.
Ensure that:

  1. You compiled your Flash application with debugging on.
  2. You are running the debug version of the Flash Player.

I downloaded Flex builder 2 but is there anything i need to do, PLEASE HELP GUYS.
