Thanks you for contact us about the theme.
The theme ves shopspa we dont use product page builder to build the product page layouts. We use common phtml files to create layout for product page (go to app/design/frontend/ves_shopspa/default/template/view/common/view/)
If you want to build product page layout. It will work as page builder but you should assign it to product item or apply for all products in type (setting in system > configuration of ves product builder)
Please view our tutorials about pages builder at here: http://www.venustheme.com/category/ves-page-builder-tutorials/
