Hello, I saw someone posted something about DAZ's money back guarantee, but I am not sure if it was legit or just someone making comments. In my opinion there is no difference between 5.0 and 5.5 NO faster Renders, and I am on a relatively fast graphics machine. The DAZ Studio is sporadic and does not work with Bryce correctly. Basically I paid $79 for a bunch of textures and terrains that were supposed to be free. I definitely would like to opt for the money back guarantee if one such exists.. Thanks, Brian
