That's interesting. Maybe they're fine with just having the their Circuit City logo at the top of the GnF page when entering that way? *shrug* Could mean nothing.
It means your browser is using a CACHE COPY of the GNF site instead of downloading a new one.
Do this:
Go to the CC website At the top of your browser, click Tools Then click Internet Options In the center of the page under Temporary Internet Files click Delete Files
Then proceed through the CC site to the GNF site and the banner should appear.
