GoZ max problems!

Hey there

I am having trouble with GoZ and max–

I have zbrush r4 and 3dsmaz 2012

I have a model rigged and textured in max–it has a multi/subobject texture on it. and it is rigged

I hit GoZ in max send it to zbrush…messa round with the polys…move them ever so slightly

Hit GoZ in zbrush

the zbrush version comes into max with its pivot different to when it is originally sent out .
and doesnt have any of the initial rigging…

What dont I know… and what am I doing wrong…

Thanks for any input in advance!
