Nothing happens when I click the "Add a pricing plan" button.
Most of the time, this means that there is a plugin/theme conflict.
Before anything else, you can try deactivating all your plugins (except the Responsive Pricing Table) to see if it solves the issue. If it does, reactivate them one by one to find the culprit. Also try switching to the default WordPress theme to see if it works.
