Can I ask were are your from? Or do you use any proxy settings?
And what browser and version do you use to login?
By me (Hungary) it works as it should.
EDIT: In Opera 10.51 and in IE8 it works as well.
This is interesting. When I said that it wasn't working for me in Opera, that isn't entirely accurate. If I type in the password each time I want to access the site it works as it should in Opera. If I use Opera's Password Manager, I get the error message that the OP sees. It always seems to work with IE 8.
While checking for the things you asked about I found what is causing my problem.
I use RoboForm to login and it did not work using that but when I physically typed in my login information it worked fine. Tried it a couple of times both ways and RoboForm is not working to login to Norton. RoboForm does work for other apps though.
Thanks for all the replies.
By the way I'm using Norton Internet version 16.8.0.41, Firefox 3.6.3 and IE 8.0, Windows XP 32 bit
Thanks for the update and I'm glad this is working for you now.
I know this is not the issue you posted about but I noticed that you are running NIS 2009. If your subscription is current, you are entitled to a free update to NIS 2010 and I would highly recommend doing this.
You can visit the update center as indicated below to get your free upgrade. You can also (as a precaution) note down your product (license) key from your Norton Account. If you use ID safe you can back it up first by following the procedure at this link.
The above is only a precaution as most times updating from NIS 2009 to 2010 does not present any problems.
