Sorry, you may be out of luck here.
The only thing I can think of is if you were using Emote as a plug-in then you might be able to recall the state of the session by reloading your DAW project, but that would only work if you did not save your DAW project after loading the new H9000 session by accident.
There are also a few pop-up dialogs that you should see before loading a new session that can help prevent this in the future. If you’re not seeing these dialogs, it is likely that you selected “remember my choice” at some point, but this can be undone by going to Preferences > Reset Session Load Options in the menu bar.
