Vpn blocked on windows 7

Have been using Norton products for many years. Took the free upgrade for Norton LifeLock 360, on windows 7, for the VPN.  Was told current anti-virus program would update automatically, but eventually had to download the upgrade manually and now the vpn will not connect. Keep getting a message: error 809 - vpn is blocked.  Is re-install the only answer?

Have switched off Norton anti-virus firewall. VPN still blocked. 

Have turned OFF automatic re-newal following download of uprade. Would this stop VPN connecting?

Have Norton Utilities installed from earlier installation of Norton.  Could this interfere with the VPN?

thank you.
