Hello - I posted this on the GetShopped forum as well but it seems like people have a lot of support complaints so I'm more than a bit worried about not getting an answer.
Anyway - I can't seem to get category pages or pagination pages (i.e. page/2, page/3) to use the single-wpsc-product.php theme template. It's looking great on my shop home page and single product pages, but the minute you click a category or use pagination the theme defaults back to my standard theme for pages/posts and looks pretty wacky as a result. Deadline is coming up and I am not sure what I can do to fix this. If anyone can help, that would be a huge relief.
