Shader problem

[MDesign]

hello,
I test the reality server but i have a problem with shader,
I use the visualize template with a 3dsmax scene. When i see the scene in reality server, the objet dont have shader and the whole scene is pink .I see objects but the have the same material (or no material ...)
and when RS run , i have a massage like this

1.6 IMI io error: C:\Documents and Settings\Administrateur\Mes documents\reality data\applications\disjoncteur\scene\the_scene.mi_m ats.mi, 88: assigned shader "mrArchMaterial|Shader[452129609]" is undefined

I test with the cube.max file but it's the same result



Any suggestion
Thanks
