I did an import of this layout and the result I get in DW looks very close to the included png. The only thing different is the content that has been added to the sample pic.
When I added this all I did was bring up the CSS Sculptor Layout Manager and import. I then pointed to the zip file, it was named 87.zip. When I imported it I could then see the layout in the list of available layouts. I then created a new CSS Sculptor page from this layout and got the result I was expecting. I'm including a screen shot of what I got.
Did you get the correct result with the Middle Earth preset?
