Well, I suppose a good place to start would be to delete H9 Control's properties file, which is under C:/Users/your-user-name/AppData/Roaming/H9 Control/h9_settings.properties. (AppData is a hidden directory; you'll need to adjust the settings of Windows Explorer to see it.) You'll need to kill those three running instances first so they don't recreate it and then after deleting that properties file, you should restart your computer.
