If you are running Norton Personal Firewall, or if you have Privacy Control activated, please do the following:
Double-click on the SSL-Secured icon (the padlock) in the lower right-hand corner of the online library screen. The Certificate Information screen will appear. Double-click on the Install Certificate icon. When the Certificate Import wizard appears, install the certificate by clicking the Automatically Select button. Continue through the Install wizard by clicking next, etc.
Open Norton Personal Firewall and deactivate the Privacy Control, so the status reads "Off."
Restart your computer. You should now have full access to the online library.
