In the file I had you download, navigate through these directories -
then find and open the file named 'newpoints_shop.php'. Open it, Ctrl+F, then search for 'version' and tell me what the two numbers in the quotes say.
Should be something like this - "compatibility" => "x.x"
I forgot to mention, if you're not using the most updated version of NewPoints update to NewPoints 2.0 and nothing below.
