I also had the same problem some months ago. Used all the contact rules but got no reply for a very long time (consequently, I didn't make the purchase I was planning to make). Some time later, Nick posted a thread in this forum (his alias here is AsileFX also) and I used that opportunity to complain about it in the thread and he replied that he had been getting email problems or something. Whatever it is, he's losing business with this situation.

I suspect (although I'm not sure, I'm just speculating as I never saw any of his DVDs) that the "real trees" technique includes ecopainting the normal leaves of a tree with more isolated leaves. This gives a feeling of very lush trees and hides the ugly planes, so typical of Vue trees.
