4ds tools problem

Hello everyone, i have a problem with using 4ds tools.

I have 4ds Tools 2.1 installed on my pc, and 3ds max 2012 too. im currently running on win7. Importing scene.4ds works fine, but when i try to export it, it always gives an error (check attachments). Does anyone know how to solve this problem?

Export script has many bug and works rarely.I think its not a time for it.
Which scene.4ds did u import?

I tried to export arctic1 and czech6, both had the same problem. I think it would report the same error in any scene.4ds. Anyway, thank you for your respond, and btw do u think that its better to use ls3d editor.gup? Because i think its not working too for me ...

Dont know.I dont work on LS3D editor.I think Unity3d better)
I started project for new hd2 yet on new engine.

Yeah sure, i saw your video on how to import scene.4ds to unity, but isnt there any easier way to do that? i mean this video:

Of course i found another method.And import mesh,not a heightmap.Its easier than create terrain in unity.Best way is edit mesh in 3ds max.I dont make tutorials now because working more
