Problems loading an AS2 swf

Hello,

FILE1.SWF (AS2) that loads it’s variables from a .txt file using

LoadVariablesNum("variables.txt", 0);

file1 has a dynamic textbox with a var from variables.txt

FILE2.SWF (AS3): AS3 SWF that loads FILE1.SWF:

import flash.display.*;
 import flash.net.URLRequest;
 //definitions and laoding default clip
 var rect:Shape = new Shape();
  rect.graphics.beginFill(0xFFFFFF);
  rect.graphics.drawRect(0, 0, 800, 600);
  rect.graphics.endFill();
  addChild(rect);
  var ldr:Loader = new Loader();
  ldr.mask = rect;
  var [url:String](http://www.kirupa.com/forum/String) = "\FILE1.SWF";
  var urlReq:URLRequest = new URLRequest(url);
  ldr.load(urlReq);
  addChild(ldr);

Both are in the same folder. Problem is that variables are not loaded into the textbox when FILE2 loads FILE1.
In AS2 i could just do loadMovieNum(“FILE1.SWF”,1); and everything would be fine.

Is a problem with levels?
