Hi, First off, you'll need to be using Artisteer 3.1, so upgrade if that's not the case.
If you are using 3.1, are you sure you used the correct delivered Artisteer skin? It all depends on the position of your menu, header, and footer. I can't be sure what your layout is without looking at the .artx file, but from the graphic if seem like you have:
- header outside sheet
- menu outside sheet above header
- footer inside sheet
I cross referenced this on the Creating Skins with Artisteer. Given this combination, you should be overlaying the artisteer31-blueonblue skin. Is that the one you used?
