I have never experienced that senario before so can not offer help with that one. Sorry.

Was it 3D Studio Max that deleted the runtime folder called textures? or did it happen when you open Poser?

I would open the runtime that you created and make sure the paths are the set up that is default for Poser. You might have a mispelled name on a folder or double folders.

Also did you use the default button and save the defaults the way I have them checked or unchecked in the second image I posted? If you did not then Max will use it's own incorrect choices as a default. I.E. scale is set to .04 instead of .01 which will make your models 4 times as big as they should be.
