If you are accessing the internet via a proxy server, first make sure that the proxy address and port settings are entered correctly in HTTP Settings. If you have a direct connection to the internet, you can leave the proxy address blank, otherwise if the correct address is not specified, SiteMapper will not be able to connect to the Internet. Your ISP will inform you whether you need to access the Internet via a proxy.
You may need to set the path to your web browser and other external programs. These settings can be changed in Setup External Tools.
