Creating SWF files

I am using ToonBoom to create characters for a video game Im designing and building. In order for me to turn the characters into sprites I have a program called SWFsheet It takes SWF files and converts them into sprites
So how do i go about making my TB files into SWF files? I did it accidently once a while back but can’t figure it out today

Well i figured that part out- exported it as a flash file, but now another problem has come up. the SWFsheet program needs actionscript3 files and from what i gather TB studio only produces actionscript2 files, is that correct? if so what do i do now, is there an upgrade?
