Blender won't export to 3ds

Hello I made a model with blender.
It works fine while in the blender program.
But when I try to export it to 3ds it just gives me a 26 kb file, with nothing in it.
Is this a known problem?
Is there a way to fix it?, and if so how?

p.s. my friend that has been working with me on a project only uses 3ds max…
So without being able to convert this, we will have to start from scratch,
and most likely use 3ds from the beginning =(

I think it only exports the selected object(s).
