You are running a very old version, so I recommend you update to the latest build at www.pragmasys.com/ssh-server/download. You will need to uninstall, then perform a fresh install. You can save your settings using regedit.exe to export our key HKEY_LOCAL_MACHINE\SOFTWARE\PragmaSystems. Keep in mind if you use the registry to restore your settings, you will need to install in the same place as the prior installation.
