The "missing" file (which is not actually missing) is a consequence of having that spurious file in the includes/modules/payment directory. Move it to where it should be and Zen Cart will no longer go looking for a matching language file and things should become a lot less confusing.
OK... I'll move that file into includes/languages/english/modules/payment/autoload.php
From what you're saying I'm wondering if I should simply "copy" it over there but, I'll give the file move a go and see what shakes...
