Recently I worked on a project in which I imported a collada .dae object(exported form Maya). But it gives me an error that: 

Exception in thread "Animation Thread" cooladaLoader.ColladaLoaderException: WARNING: the actual file is made by Google SketchUp 8.0.14346 and not 'Google SketchUp 8.0.3117'. It might contain a different XML-Structure

 throwed by a java.lang.NullPointerException. 

 

after that i made second .dae file in sketchup free version, then it gives again an error: 

Exception in thread "Animation Thread" cooladaLoader.ColladaLoaderException: Google SketchUp 8.0.3117

 throwed by a java.lang.NullPointerException

 

I dont know .. how to solve it..

Any suggestion must be appreciated .. 

Regards..
