Could you not load it? Were the components of your designs mixed up?

Failed to load, SEIV told me I'm using the wrong data files.

Did you add any new racial traits? If you can't load the savegame something very basic/important of the data file has been changed. Adding of new components/facilities alone will not cause this.
