Is anyone using this program?

It looks neat, but I can't get it to work unless I use the default
SYSDBA/masterkey password combination setup. If, for example, I
change the SYSDBA password to something else in both the program and
the DB (via IBConsole), I get a "Username not defined" type message
when GBak runs.

The authors' email address has expired.

Any clues?
Win95/Firebird 0.9.4.41/GBak Scheduler V1.0

Thanks,
Steve
