Some render/color settings changed on my model after 4R7 install

When I installed 4R7 my render settings changed on a few files. A purple color on my model that was human flesh looking but blue is now very shiny like metal. How can I have my exact 4R6 settings back in this regard?

Further, what is strange it did not happen with every model, Just the one I was working on last. I wish I could show a picture but I don;t have permission. This is retopo job I was doing for somebody that is working on a game.

Thanks,

Robert
