Hello. I've installed a theme designed to support Core Commerce and the layout is not formatted to the screenshots on the page (eg homepage screenshot has several images and columns which don't appear - it's just blank).

When I go into the store item areas and choose a different page design, all of the content just disappears and I'm left with a blank area. If I go back and choose the original design, it doesn't revert back.

Any idea how I can wipe or reset my site so that the templated theme is identical to that in the example? I thought that way I can use that as a 'launchpad' to edit.

Thx!
