I’d missed the scrolls on the mat files, just noticed there weren’t any on the earlier files. They are .dsa so there shouldn’t be any problem with their being tagged as a later version. Please check the end of your log (Help>Troubleshooting>View Log) juts after applying a preset, to see if there are any error messages, and post a screenshot of the Surfaces pane for one of the materials - say SkinFace.
You shouldn’t, in general, need to apply the shader - the .dsa files will do that for you (if they are working in your version of DS).
