flash player 10 - effect not working

Hello,
i have a main swf that has buttons which load other swfs via the Loader class (these swfs contain flasheff2 effects). I used to publish for player 9 and everything worked fine. Now i am publishing for player 10 and the loaded swf files which contain flasheff load until the effect and just stop (as if i had a stop(); command).
I have seen other posts that seem to have the same issue but they have not been answered.
Flash and flasheff2 versions are up to date. Again, everything worked fine in player 9 ad only the swfs that contain flasheff freeze.
Any ideas?
thanks
