If you’re able to bypass Cineplex’s initial security warning but still see an error when you try to play movies, it’s likely the service has detected your VPN somehow. Your best bet here is to activate a stealth mode if one is available, try a couple of different servers, and clear your browser’s cookies to get rid of any old location data. Failing that, ask the VPN’s support team for help – they’ll be able to tell if the problem is on your end and help get you back on track.
