error: password is incorrect when checking My Network with My Norton Account

hi! 

Have a :

PC:  Dell 

OS:  Windows xp Home Edition 32-bit SP3

Anti-virus: Norton 360,  it has no version number

When I want to open my Norton 360, Settings, My Network, Detailed Settings I enter my Norton Account password;

An ERROR widow opens saying "The Password is Incorrect".

I have retried a dozen times this past 2 months,

I have changed my password,

still i get that same error notice.

Question: How do I get to have my Norton Account Password to work so I can get into my Detailed Settings?

Thank you
