All I know is that it referenced material that was not present in the one I downloaded four days ago. So why yours works well without any problems and I had to change the cr2 is anyones guess. As far as how it works once I modified the cr2 I have no complaints about it. It seems, however, that there are a few people who are not happy with the Cd they paid thier hard earned money for and if they can't contact the person who created and sells the Cd (and I did a very thorough search of his site) to ask about thier concerns one can't blame them for venting here about it. After all, a hundred bucks is a hundred bucks which could buy a few other Cd's with some pretty good stuff on them right here at Renderosity. :)
