No VPN service for months . . numerous fixes tried .

I have not been able to turn on Norton VPN for several months.  I have tried various solutions including uninstalling then reinstalling Norton 360 numerous times.  I can only assume there is something blocking this part of the Norton package since every other part of the product works.  Anyone have any fixes?  I am not particularly tech savvy although I my son is so if it requires fixing a registry or wlan setting or something, I'll have him do it . . .

BTW, it works on all of my other devices and I no longer get the error message that says to try later . . .it just says I am unprotected . . .
