URGENT: Products Page Stopped Working

All of a sudden when you go to my products page it just says [productspage] and that's it. I need the products to be listed again as we just launched today. Please help.

On a similar note, I would like my "store" and my "products" to be the same thing. However, when I try to make both "store and "products page" both go to the "store" URL and I put [productspage] in the Store page, it just shows up as [productspage].

The urgent thing is just to get my products to show again. Over the next few days, however, I'd like to migrate everything to the store. Please help. Thank you in advance.
