ATN: TESTERS and other Vue users who may know.

I have a customer who has Vue6 Extreme and it seems the "Ruined Suburbs" sets and some of the individual Nuked vobs are not loading.  He is getting this error which I don't understand:

***"When I go to import Destroyed Suburbs 7 it asks me for a "plantwinterpear1.mat" file of which none was included, and none are available in my current Vue 6 library of items."

***I thought that Vue shipped with the plant mats as default?
You guys figured out the problem before and helped me, got any ideas what I should tell the buyer?

Thanks
