How Can I Resize A Swf File That Loads Contet From .Xml

The banner contains main.swf file that loads content and images from gallery.xml and images folder. I also got source files main.fla, and soe Action script files (Main and Time Slide).

Dimensions of main.swf are 960x360px and I want to resize it to 550x385px. I tried to resize main.fla source (Modify -> Document) but wen I resize it it just cuts right part of the banner and content on the right is cut off.

Please if someone can help me, it is URGENT, I have to deliver web site to the customer ASAP. :(

I feel it is something simple, but I can’t figure it out. x(

Thanks in advance. :)
