Strange results with more than 360 degree rotations

I have a certain rather simple 3ds scene that doesn't export through the plug-in well. The scene includes a complex but static scene of billboards, street, buildings, subway station and one non static small plane that represents a camera walking around the subway and then exiting to the street and looking around at the buildings.

I think that the export problem has something to do with rotations of more than 360 degrees by the plane.
If I cut the animation keys, after the camera exits the subway and turns around, the scene exports correctly. The second half of the scene also exports correctly on its own when I remove the keys in the first half

Does this sound familiar to anyone? Am i missing something in the plug-in options? The 3ds scene compresses to over 1 meg so I can't send it but I just tried another export that works really badly, I'm attaching it instead (News.3DS).

If need be you can contact me via email and I'll send the scene over.

That is not the bug of kw

That is not the bug of kw x-port plugin. That is the limit of 3ds Max. You must use the dummy object in Create/Helpers and "Select and Link" from the plane to the dummy object. And then rotate the the dummy object with the degress over 360(by Autokey or Set Key). But I am not sure kx x-port plugin support the dummy object. You can try it. If you are successful, please reply the post.
