How do I completely reset Ghostwall

Hi, I know if you delete the .fir file in windows\system32 you get a new default rule set. But I have a different problem. I originally installed Ghostwall on a server with 2 NICs (192.168.x.x and 10.0.x.x) and everything was fine. Now I have removed the 10.0.x.x subnet from NIC#2 and changed it to external cable modem IP address (203.96.x.x). Problem is that Ghostwall still fires up with the original 2 subnets. How do I get Ghostwall to re-read the settings from scratch. I have completely uninstalled and reinstalled and that doesn't help? Thanks in advance.
