Why does DAP fail to connect and start download?
If your internet connection is configured to use a firewall, please make sure to configure the firewall to allow DAP full access through it. If your internet connection is configured to use a proxy, open DAP’s main window, click the Tools menu, and then click Options. Select Proxy/Firewall, and then select the Use HTTP Proxy, and if necessary Use FTP Proxy. Enter the same proxy address and port which are used for your connection.
