Exporting AS?

Hey guys,

I’m quite new to Flash, so pls bear with me. This is either going to be a really simple solution or a hard one.
I completed the snow tutorial:

Now i would like to export it as a quicktime mov. But everytime I export it, the screen is blank, except for the white dot on the screen.

How do I export it as a *.mov, and have it animated at the same time?

Please reply ASAP, as my assignment is due VERY soon!!!

Thanks!!!
