MediaDisplay causing script errors

Hello,

I've used the mediaDisplay component before and had no trouble with it, but now here is my prob:

1.USING MX 2004
2.I create a FLA called "test" which has a mediaDisplay and a button.
3.The button has this code:

on(release){

loadMovieNum("test.swf",1);


}

It calls the same file to load on level 1.

When I click on the button it freezes, and gives a script error.

Now, this works perfectly without the mediaDisplay.
It was working fine before with other files (not the test file i mean), but I wanted to edit the files and it started to freeze.

Please help me out.

Thanks in advance,

Loo
