Autorefresh external dynamic text?

Hi,
I created a flash that’s loading dynamic text from an external txt file.
It’s ON AIR flash that you can see on top right on www.topfm.rs

Now the thing is that I WANT THIS TXT CONTENT TO REFRESH AUTOMATICALLY… because I am actually loading txt file that’s getting updated every few minutes, but flash content does not update, so the visitor must refresh page on go to some other page so the content will change again.

How do I make this work so that dynamic text in flash change whenever external txt file content change, without refreshing or changing the page.

I am attaching .fla file for this so that you can see my code and probably help me…

Tnx!!!
