Problems with older blender versions and 3ds exporter

I made my 3d model with new blender 2.62,rendered it with cycles.I created also file with blender standard mats.Then I want it to open it with older blender versions 2.54 or older blender 2.49.When I open it I have only lowpoly wired model on my viewport.I tried to press z to change in to shading model.When I press to render it it shows me empty final render.:eek:

Another question is when I export it from blender3d 2.62 to 3ds and import it in glc player and on 3d via online player I’m receiving distorted mesh object.My tires are bigger then carbody.All objects are messy…I had to pull my latest 3ds files from the 3d markets cause this problem.Thanx in advance for your help:p
