Found the fix for this. You have to edit the plugin file (either from WP admin or in wp-content > plugins > gotowp > gotowp_personal.php). There is a call for the validation script file that is incorrect.
Change this line:
wp_enqueue_script(‘validationjs’,plugins_url(‘/gotowp_personal/javascripts/jquery.validate.js’));
to this:
wp_enqueue_script(‘validationjs’,plugins_url(‘/gotowp/javascripts/jquery.validate.js’));
That will fix the link to the validation script.
