lost Symantec content licence after system time change

hello group,

I have newly installed ibm lenovo computer with oem Symantec AntiVirus
10 and Symantec Client Firewall 8. The system was installed on March
23 and then it showed that Symantec licence is valid till Jun 21, this
year. It all worked well, definitions were updated timely.

And then for testing needs (my job includes programming) I changed
system time back and, errr, then put December 2007. And, besides some
other apparently scheduled events, was "happily" announced that there
is no content licence on my computer.

I turned to Symantec webpage to get know that their support has become
quite unavailable for common users.

Am I complaining, am I asking for help in this message?... but if
somebody has some useful comment (concerning Symantec), I would
appreciate.

Andra.
