You need to contact your VPN service provider, apparently nVPN. That is the organization which gave you your configuration files, and perhaps a username and password, and to which you are probably paying a fee for VPN service. For more information, please see Getting VPN Service.Tunnelblick is just the free software that many VPN service providers recommend or supply to their customers. We do not provide VPN service, just software.
