Flow Items imported shape don't appear on other computers

Greating,

I am actually working on a model that simulate crossroads, my problem is that the imported shapes (cars) can only appear on my computer.
Because I import shapes that were exported from Sketchup on .3DS extension I thought I would solve the problem by exporting on .WRL extension, but on that case, I can't even make the shapes appear on my own computer.
Can any one help me?

Thank you in advance.

I finally made it work by importing the shapes into flexsim using the original Sketchup files (.skp) instead of (.3ds). The model is a lit bit slow, but at least we get to see a resonable simulation.
Thanks any way
