Store not Functioning Correctly

Hello, just installed Market Press and some of the pages are not loading correctly, or just blows up.

For instance, the store page loads generic, how do I get it to display my products?

http://krministry.org/store/

The product overview page blows up:
http://krministry.org/store/products/

The Category page loads, but when I veiw an item, I dont see any details like price, or how to Add to cart/Buy

http://krministry.org/store/products/category/shirt/

Not sure what i'm missing but this doesn't look like Shopping Cart, just blog posts.

Please advice?
