Flex Builder/Papervision Lib problem

Hi guys!

Im having an issue with the papervision lib in flex builder and nobody could help me so far. I had created one lib with all the papervision classes in flex builder, but in one of the classes in the unitzeroone folder, theres a class that embed a swf file.
Every time i try to compile any project with the papervision lib, the flex builder trow me an error like “unable to solve…”. The projects works fine, but im tired of this error. I tried everything, from change the file folder to change the way its loaded, but anything seens to solve the error.
Can you guys help me?
