If you have a SWF created by Catalyst, and you're using that SWF in something you're creating with Flash Builder or Flash Pro, then I think frame rate shouldn't matter. But maybe if you can give more details I could help more... Which flash program are you importing the SWF into, what commands or code are you using to do the import? Is there an error message or alert, if so what does it say? Any info you can provide will be helpful.
