Malwat, I had two people look at the product and it worked in both people's computers and they both had DS 4.9 with the latest update, and one of them did notice that the material files weren't loading like you said. One of the people said they would see if they could fix the files. While the person is seeing if they can fix the files, I'm going to email the freestuff provider and see if they've updated the product since 2011 and see if they can upload the updated product to the freestuff area or send it to me. So this is the update I have for now. If you have any questions, then feel free to ask me. I hope you're having a great Tuesday!
