Rating system for marketpress' products

Hi!

For some obscure reason, the plugin I use to allow users to rate products, WP Customer Reviews (https://wordpress.org/plugins/wp-customer-reviews/), is not working. Before going through all the plugins and theme conflict test, I'd like to know if one of you guys could take a look at my site and see if you detect the cause of this, as deactivating my plugins almost always ends up generating me new issues -I know, it's bizarre, but like one of you guys already told me a few times: my site i a zoo, haha :stuck_out_tongue:. Here's a product's page, that should display the 5 stars rating system:
https://www.wheelofcommerce.com/johanschneider/store/products/beach-9/
Here's the settings page for the plugin:
https://www.wheelofcommerce.com/wp-admin/options-general.php?page=wpcr_options

I use New Blog Templates; can it be that? Should I set up the plugin in that account instead of through the admin area?

I've contacted the plugin's dev, but since the WPMU's staff already has access to my site, that makes things far easier -I've sent my credentials around 1.5 - 2 months ago, with Aicee's name on it. If there's no way to make the plugin work, I'd like to know what my plugin options are.

Thanks.
