Can't login to Norton Family from Mac 10.6.8 to finish installation

Hi,

I'm unable to install NOF on a Mac running 10.6.8 Snow Leopard. It previously ran NOF, and I upgraded to latest version - however at the end of the install it won't login to my existing NOF account - it then prompts me to create a new NOF account - but again doesn't seem to be able to connect to NOF to validate the login.

If I re-start, NOF is installed, but not logged in. On trying to login I get a 'noConnection' message pop up.

 

I've tried uninstalling and re-installing, restarting etc. I've also tried running the norton removal tool and re-installing. However, always the same outcome.

 

hope you can help!
