I have loaded NS Pro 2.1. I am running Joomla 3.5.1 with php 5.6.16.
I have created 2 newsletters (id's 1 and 2).
I then used Toolkit, Tool #3 with my email address and newsletter ID 1. When I click "Send Newsletter" I get an error "Newsletter ID not found".
I set up a very simple newsletter - id = 2. The result is the same.
As our time zones are very "far apart", I have taken the liberty of sending you a private email with details to access the site backend if you need to.
