Most often, this is what helps - start Internet Explorer (I mean IE, not another browser!), From the menu bar, click Tools - Internet Options - Advanced tab. Open its settings ("browser properties") and there, on the "Advanced" tab, make sure that the checkboxes opposite the "Use TLS 1.1" and "Use TLS 1.2" options are checked ... If in Internet Explorer, the site https://www.bolidesoft.com (where we have an activation server) opens without warnings and errors, Bolide Movie Creator activation should also pass fine.
