How to quickly resize banner ads created with tweenlite

Hello all,

I was wondering what the easiest way to resize banners that use Tweenlite or any tween class.

For instance I have a 300x250 and I need to resize it to 640x480. Is there a quicker way to resize it with out resizing and moving all the movie clips, then reediting the code for the x and y coordinates? Most of the assets are vector so resizing the whole .swf isn’t an issue.

I just can’t think of an easy way to do it without redoing everything.

Maybe there is a program that works for just this purpose…

Please help!

Thanks so much,
