Help me.. I have multiple files to pack.. An supporting xml file for main swf file. I have created .nfl package as given here. But when I run the game on device.. getting output as "File not found".

Here is the code I used to read the xml file...

var texts4game:XML = new XML();
texts4game.ignoreWhite = true;
texts4game.onLoad = function(success:Boolean){
//code to display in text fields
else gameh_txt.text = "File not found";

getting output as "File not found". I tested without creating packages, directly deploying swf and xml file, this is working fine.
Do I need to make any changes to the path of xml file used in Load function.
Do I need to make changes in descriptor.inf file or any settings on winzip before compressing to zip file? Please help...Thanks...
