Cannot connect to the Norton server

This thread is related to "Switch to Norton Security Deluxe from AVG" in this section.

Thanks to everybody's help I subscribed to Norton Security Deluxe, uninstalled AVG, and installed NDS on three PCs.  On the last PC I was able to do a Live Update (and rebooted), but when I click on Activate Now I get the timeout message "Cannot connect to the Norton server". 

In My Norton I see that two devices are subscribed.  I can't find any way to get the third PC recognized.  Obviously my Internet connection is working, as I was able to install NDS and do an update.

I'm using Windows 7 Pro 64 bit SP1 on all three PCs.

Help!
