There is a URL:
http://www.symantec.com/region/reg_eu/techsupp/ where you can try the
Subscription Troubleshooter on the RH side. The area on the LH side, takes you to:
http://www.symantec.com/region/reg_e...t_options.html where you might be able to find what you want.
If urgent, you could probably update
here. LiveUpdate file download info is
here. Symantec unfortunately are not over helpful with letting you know what to do when you have a problem.
For Symantec there is a UK helpline number: 0207 616 5600. It’ll be “press 2 to speak to…” to begin with, so make sure you have a comfy chair handy. It will help if you are in front of your running PC at the time, but obviously if you’re on dialup you won’t be able to connect online, as you’ll be using your phone line. It is best to have any account numbers and registration numbers, proof of subscription (if you have any) so that they can confirm your status. Your old number should be on the renewal e-mail for last year if you bought it online.
There are other options, so come back if this doesn't help.
