Help with error

[mark goldin]

This is the error I am getting:

ArgumentError: Error #1063: Argument count mismatch on
mx.resources::ResourceManagerImpl/installCompiledResourceBundles().
Expected 3, got 4.
at mx.core::FlexModuleFactory/installCompiledResourceBundles()
at mx.core::FlexModuleFactory/docFrameHandler()
at mx.core::FlexModuleFactory/docFrameListener()

any idea what that might be?

Thanks
