None of store pages are loading in marketpress

None of my pages load. I have completed the set up, added a product, and still the only thing i can see when i try to load any of Marketpress pages the only thing i can see is a white page with the cart up at the top. I can view the product from the dashboard. and my tabs for the store are all linked to the correct link, but not even the url links for store, products etc. are working.
