    import flash.display.Sprite;
    public class TheSimplestPlayer extends Sprite

Answer 1

Its silly I am answering my own question . But I added playerglobal.swc file under lib and thats how it stopped working , I removed all additional swc files and that fixed the issue .

Thanks for all your help .
