Cannot Access Norton Update Center

Dear All,

I juts bought a new laptop and installed a CD version of NIS.  The installation went smoothly, and I can also download various updates through the Live Update.  At one point, I noticed there is an update icon on the right side of NIS main screen.  After clicking on "Get the Update" button, the program brought me to norton update center website.  However, it seemed that I cannot access the norton update center website (whereas I can do normal browsing - google, youtube, and stuffs).  I alway got the message "server not found".  When I tried to access norton update center by manually entering the address in the browser address bar or through norton.com - support - norton update center, the same problem occurred.  Oddly, I do not observe the same problem in my husband's laptop or his gaming pc whatsoever.  Can anybody help me to solve the issue?

I also noticed that normally, my e-mail would appear in the applications main screen.  However, after reinstalling NIS to troubleshoot another problem, I noticed that the e-mail address no longer appear.  Is this issues related to the above?

Thanks in advance.  Hopefully I can get some directions to solve theses issues.
