Timeline preloader works, but not online

I made a preloader in the timeline and this works perfect when I test the movie…
When I put it online, it gives me tons of errors…BUT… a guy (for who I made this preloader) has his preloader working, exept in InternetExplorer its only working one time, in firefox it works like a charm.

His FLA is exactly the same as mine, but at his site you dont get errors, except that IE thingy.

You guys can take a look at the working example that he published.
And heres mine, even if you want to look at the [URL=“http://creator.be/storage/as3Preloader/as3_preloader.swf”]swf it gives errors.
you actually never see the swf except if you dismiss all errors and go forward and backward and even then only partially.

Offcourse you can also download the used FLA.

I did some searching at the forums, but all I see is people that say it must be an externa script for the preloader, but …why is mine working when I test it and is his swf working (almost good) ?..

Thx for reading anyway.

regards.
