I'm having some issues with Knossos after not playing the game for a long time. Is there a way to reset the path to the retail data? I can't load anything because the game exe (which is in the Knossos library folder) doesn't detect the retail files.
First, close Knossos, then assuming you're on Windows, go to the "Run..." menu (Windows Key + R), type %appdata%
and press Enter, then rename the folder knossos
to, say, knossos_old
The next time you start Knossos, you should see the "first run" welcome wizard.
IIRC the equivalent folder on Linux is ~/.knossos
and I think it's ~/Library/Application Support/knossos
