This usually happens when you try to connect directly to Live Homework Help® without going through the LHWH link on your library's website.
To use Live Homework Help®, you must access the service by visiting your library's website and clicking on the Live Homework Help® link or icon. You cannot load the Live Homework Help® entry page directly.
Also, please make sure any Internet firewall and/or security software on your computer is set up to allow you to connect to Live Homework Help®. Most problems are resolved by allowing the firewall to pass referring URL information to web servers and the ability to send/store browser cookie data.
