If there isn't a configuration file (caesar.cfg) available, nothing will work. The default CFG file is created during installation (did the Configuration Module come up for you then), and the file is written to "c:\documents and settings\all users\application data\coade, inc\5.20\system". Make sure the "caesar.cfg" file is there.

When you try to start the Configuration Module, does it display? If it doesn't, are there any error messages displayed?
