Message if the buttons are hidden

First, love the plug-in! Easy to instal and is working perfectly. I was curious if there was a way to add a message along the lines of: Please login to see prices and purchase.

I see in the plugin:
if ( ! defined( ‘ABSPATH’ ) ) {
echo “Hi there! Nice try. Come again.”;
die();
}

But right now its just not displaying anything.

The page I need help with: [log in to see the link]
