Flash banner on website wont load until browser is refreshed??

Question

I am having this problem on a website where the flash banners for each  page wont load in any browser until you either refresh F5 the page or  try re-clicking the page nav links a few times. Once loaded they are fine, but if browser's cache is cleared, no go. http://udornthara.com
Some research suggested "Usually this happens if there are a lot of  linkaged objects in the library with 'Export in first frame' option  enabled. If this is the case, please disable this option. The problem is  not in the quantity of the linkaged movieclips with 'Export in first  frame' option enabled, the problem is the size of the objects which are  linkaged."
I have de-compiled the SWF and checked out the library, but really have  no idea in regards to Flash files and their construction as to what is  or isn't an issue.
If anyone has any information on this problem, advice, or steps to take, would be much appreciated.
The file has 4 images, 8 shapes, 7 frames (of which 0-6 are 'loading...') and 5 scripts.
Many Thanks...

// Action script...
// [Action in Frame 3]
bar._xscale = 1;
// [Action in Frame 5]
bar._xscale = 100 / getBytesTotal() * getBytesLoaded();
_root.display = math.floor(100 / getBytesTotal() * getBytesLoaded());
if (_framesloaded == _totalframes)
    play ();
else
    setProperty("", _currentframe, --_currentframe);
    setProperty("", _currentframe, _currentframe);
    setProperty("", _currentframe, --_currentframe);
    gotoAndPlay(_currentframe);
} // end else if
// [Action in Frame 6]
gotoAndPlay(7);
// [Action in Frame 7]
stop ();
