8504,104 error and Norton 360 won't open

Hi

I have had a problem with Norton 360 since Windows 8 was updated a couple of days ago.

I cannot open Norton 360 at all I cannot open anything associated with Norton 360, no updates,no vault, no scans. I'm not even sure my PC is protected. It is showing a message : "Norton Autofix, error found, Norton 360 has encountered an error. Error 8504,104."

I have a HP Envy dv7 Notebook Pc, windows 8, 64 bit.

My Norton 360 product expires Mar 28 2014.

This problem has been going on for several days. I would appreciate any assistance.


Regards

Colin
