I downloaded 18.104.22.168 and installed it over my existing App Studio version. It finished installing. Now it will not run. When I try to open the executable, it does nothing at all - no error message. I tried contacting NSB support with no success. On your contact page, the 888 number is wrong and the support email that is listed is also wrong. When I called the 416 number, all I got was a message saying to send an email to firstname.lastname@example.org. This bounced back with a message saying it was undeliverable.
