In order to solve the problem, go to Start > Control Panel > System and Security > Windows Firewall > Allow a program through Windows Firewall and check the box next to Tout sur les verbes Anglais. If you can't find the application in the Allowed programs and features window, press the Allow another program button, navigate to the installation directory, select the executable file and press Add. Next, from the Advanced Settings select Inbound Rules > New Rule. Check the Port box, click Next, select All local Ports and follow the self-explained steps. Also, check if your security program doesn't block the Tout sur les verbes Anglais connection.
After that, open Internet Explorer, navigate to Tools > Internet Options, click the Connections tab, press LAN Settings button and make sure that box below Proxy server is not checked. If you still receive the error message, reinstall the software and try running it using Administrator rights.
