About a week ago my license for Norton was due to expire so I bought and applied a new license key.
This morning after installing the 61mb update that became available last night I rebooted and Norton said my key had expired.
I logged into my account and found out that somehow the update had also "reverted" my license key to the old expired key, and I had to re-apply the new key ... a bit of a bother.... I have several computers using NS ... I will have to see what happens to those when I update them....
