Problem with Error 5005 and with external SWF loading

Question

I am creating a relatively simple 10-12 minute animation. I've broken the animation into 34 different movie clips that I control on the timeline by using a timer delay.
When I try to export them all together I get the error:
",Line 1: Error 5005: Unknown Error optimizing byte code."
However, when I split the presentation into two halves with the same exact frames and code I don't have the problem.
I thought loading an external SWF at the end of the first movie would be a good way to connect everything. However, the SWF continuously loads and won't play through the way it looks when you open the actual SWF file.
This is my code for the external loading:
var xpos:Number = 0;
var ypos:Number = 0;
var swf:MovieClip;
var myLoader:Loader = new Loader();// create a new instance of the Loader class
var url:URLRequest = new URLRequest("aamc-2e-slide1.swf");// in this case both SWFs are in the same folder
myLoader.contentLoaderInfo.addEventListener(Event.INIT, doneLoading);
myLoader.load(url);
function doneLoading(evt:Event):void
          trace("doneloading");
          swf = MovieClip(myLoader.content);
          stage.addChild(swf);
          swf.stop();

Answer 1

I have the same/similar issue whether the stop is there or not.
Yes, it is all on one frame.
Without the stop, the SWF just continously loops on top of itself.
