Hmm? I have no idea unless it was an old swf file or one that does not import properly. I tried not too long ago to import a fairly old swf file and the import filters did not recognize it.

I am not sure if you can do this but you might have to open the swf file in another program specifically for Flash, then export it.

But that is only a guess. One of the Flash experts needs to have a look.

How large is the Flash file? You can attach an .swf file here up to 5MB. Maybe one of the members can take a look and see if she or he can get it to work.
