MarketPress - custom menus

I have a share hosting instance of WP 3.0 where I installed MarketPress a while ago to test some things out. When I installed it, Product Page, Product Categories and Product Tags options showed up in the Custom Menu builder, allowing me to create menus that link to product categories, products, etc. [see custom-menu-product-options.jpg]

I have now set up a virtual server hosting instance of WP 3.0 for production purposes and installed MarketPress ... but I don't see the Product Page, Product Categories and Product Tags options in the Custom Menu builder. [see custom-menu-no-product-options.jpg]

Is this a configuration issue that I need to tweak on the server, or is there perhaps an update I need to make to the database to get this working?

Thanks!

Bill
