Plugin Causing error on checkout account creation

I really like the plugin for the registration form but this plugin has caused guest checkout to be a problem on my site. I had a customer report this and when I tested I found that if someone where create an account via checkout it would result in a blank woocommerce error on the checkout page. After removing the plugin the error went away and the account was created. Is there some way to add the captacha to the checkout form when someone is creating an account or have the captacha not required for checkout account creation? This is for both Woocommerce 2.4 and 2.5.
