I have just installed a Norton software update after a window from Norton popped up requesting me to do so. When it was finished I was asked to re-start. I clicked on the Norton re-start button and it did re-start. After logging on I received the message 'Revoked Product Key' and that led me to this Community.
I have Windows XP and I have Norton Internet Security 2010 with a 2 year licence from 27 november 2009 - almost 11 months to run.
The only possible influence I can think of might be that yesterday I ran Advanced System Care to improve the response of my computer. After running this however I used the computer for a long tome without problem. The update triggered the problem.
How do I have my Product Key reinstated?
