My slow loading flash site :(

Question

I've recently notices that i'm loosing 70% of my visitors in the first 0-30 seconds. I thinking its to do with elements of my site loading too slowly.
I have an opening animation which I think loads pretty quickly. I think the problem is occurring when selecting a button on the menu bar. It can take up to 5 seconds to load the external text files. If a user is inpatient and selects the button again this slows the process again and again.
this is the site www.videoproductions.ie
I'm very new to flash and i've hashed and muddled my way to this point. when researching this problem I know i've done lots wrong.
for example my site is all flash....bad (or so i hear)
the images have high dpi
I've used transparency
In my menu i've used button instead of movie clips.
on the up side I have done a few things right
I have a master file where a menu swf loads into
with this menu bar I load all my other swf's and text files (which load into scrolling boxes)
Where i'm having the problem is with my external text file and embedded text
you would imagen that text files would load very quickly but this is not the case.
I've come so far with this only to hit a rock ....what is the problem with the text ..I've looked everywhere and no answers on any forums
any help would be greatly appreciated...I could be loosing allot of potential business because of this

Answer 1

I wonder if i could ask for some more help ........sorry to be a pain but I feel like flash is really beaten me. Been at it the last two day going round in circles
I've attached the menu file I have a master file which is an animation then into this loads my menu swf (which is attached) with in this I've been trying to get the pages to load up on different frames and its all working ok except for loading in my external txt files.
i'm assigning the following scrip to the relevant frames to load the text files
myData = new LoadVars();
myData.onLoad = function() {
textbox2.text = this.myNews;
myData.load("TEXT2.txt");
Its working on the Packages page but only on the first click. for example if you launch the swf and go straight to Packages you'll see the text load in but if click any where else it ceases to work. i'm using the same method throughout but none of the other text files load up at all.
any idea what i'm doing wrong?
My scroll bar is no longer working either but I'll figure that out some other time
