FLASHEFF ERROR: missing from library

Hi! Well Im making a presentation using about 6 swf (loadURL, contenedors and that codes) each work perfectly fine by itself but when I want to see them loading each other I got this error:

FLASHEFF ERROR: The pattern 'com.jumpeye.flashEff.symbol.slide.FESSlide' is missing from library.

But then I check my library and its over there. I have try to do it again and its the same thing. Any ideas?

Please try to load the external .swf files by specifying the application domain too. You can find an example in the knowledge base for TxEff: http://www.jumpeyecomponents.com/knowledgebase/TxEff-AS3.0/Main-TxEff-animation-loads-external-TxEff-animations~473/.

Thank you very much!
I was experimenting so I copy the effect to the previous swf of each one and it works perfectly!
