Flash Project not playing when users go to site

Question

Alright heres my problem. I have a large flash website, that
was originally a template and I added to it. I have been able to
upload it to my server, but there is at least several minutes wait
time before the preloader came up. So in an effort to fix this I
created a Master file with 10 frames total. on the first keyframe I
have "Loading Site" in plain letters. I have the actionscript on
keyframe 1 and I have the main movie(masterP.swf) loading into
level 20, preloader.swf loading into level 50 and trigger.swf
loading into level 5.
here is the actionscript on frame 1:
stop();
//-----------------------<MCL>------------------------\\
var myMCL:MovieClipLoader = new MovieClipLoader();
var myListener:Object = new Object();
myMCL.addListener(myListener);
myListener.onLoadProgress = function(target_mc:MovieClip,
loadedBytes:Number,totalBytes:Number) {
_level50._visible = true;
var preloadPercent:Number = Math.round((loadedBytes /
totalBytes) *100);
_level50.preloader.gotoAndStop(preloadPercent);
_level50.preloadInfo1.text = preloadPercent + " % loaded";
_level50.preloadInfo2.text = Math.round(loadedBytes/1000) +
" k loaded / " + Math.round(totalBytes/1000) + " k total";
myListener.onLoadComplete = function(target_mc:MovieClip) {
_level50._visible = false;
//-------------------</MCL>---------------------------\\
//triggers the MCL to load these assets
myMCL.loadClip("trigger.swf", 5);
myMCL.loadClip("preloader.swf", 50);
here is the actionscript on frame 10:
stop();
myMCL.loadClip("masterP.swf", 20);
The biggest issue is when the user goes to that website it
almost seems as though the movie is sitting on Frame 1"loading
Site" and doesnt even reach the preloader, then when i hit the back
button and go foward the preloader is there, just looping in place
not really loading. oh yeah I have two dynamic fields on the
preloader, and it is supposed to have loading info in them, but
they do not even show up. Not sure what I should do. I am uploading
with Dreamweaver MX, I am using Flash 8, the original file was
flashmx I believe.

ok I think I fixed the problem, but i dont know how, but now
I have a new problem and I need your help on this one, the
preloader comes right up and at about 45% I get an error message:
"A script in this movie is causing Adobe Flash Player 9 to run
slowly. If it continues to run your computer may become
unresponsive. Do You want to Abort?" Also the site loads around
this time, it is NOT loaded correctly because when i click on the
buttons they go to wrong frame labels, though once the loading is
done they go to the correct one. Any idea of what I need to do for
this
