How should I remove this black background from this .fla animation? I'm using flash 8 for the first time and I just can't figure out. I don't know which version of .fla is this.

I need to make this transparent to use it on a gradient grey/white color background.

Is there anyone who could guide me to remove this black color background and make it transparent? I believe its just a couple of seconds worth of time for some who knows. I would be grateful if they can modify and upload it for me too.

thank you.
