Links to products & categories not working...

FRESH install of Joomla, VM & MyStore (quickstart). When I click a category along the left, it just comes back to the home page and does not display the products in the category. Same thing when I click one of the 9 slides in PhotoSlide in "header" position. Is there something I need to enable?

I can see where to edit the slides and I can see the categories and products in the Admin section, but can't access any of the products via the front end. Thanks!
