Problems getting CPF to work with a Sierra 595 Wireless Aircard

I downloaded and installed CPF last night. Now everytime I try to connect to the Intrnet, I get a message that the settings are incorrect on the network setup. I’m running a Dell Latitude D620 with WinXP Home SP2, VZAccess Manager, and a Sierra 595 Air card. I had to uninstall CPF to make the connection to the forum. TIA, Charlie (:SAD)
