The Windows OS pop-ups "Farmerswife Server has stopped working" are an old known side-effect of the fw Server app's "Nightly Forced - Restart". Windows OS often flags this, as the previous running process kills itself after having launched a new instance of itself and then terminating itself. Windows keeps choking on this. The results are these kind of pop-ups. Use the "X" in the top right corner of that pop-up window to close them. If you use the "Close program" button this will shut down the currently running fw Server app process, where the pop-up window might be many days old.
