Problem exporting to flash with locomotion asset

I’m having this error trying to export to flash using locomotion asset.

What should I do?

Fatal Error : ReferenceError: Error #1069: Property http://unity3d.com/cil2as::smile:efaultValue not found on class global.IMotionAnalyzer and there is no default value.
