Woocommerce product pages not found

When I click into any of the three images displayed here:
http://carolyn.marklovettstudio.com/product-category/island-scenes/
I get the error below saying not found. Yesterday the pages were all there.

The problem occurred after I regenerated some thumbnails with Regen. Thumbnails plugin.

Im using the Hatch ver 2.6 wordpress theme that I made compatible with woocommerce,
using Woocommerce version 2.0.13, and wordpress 3.6.

Here are links to the missing woocommerce product pages on my site:
