For those who have been missing SOTASpotMonitor after the passing of Eric KU6J, I have reverse-engineered the last known version to work again. This modification is done with little testing, but posting spots and monitoring spots should now work again.
You will need to right-click, save the file and rename to SOTASpotMonitor.exe. Replace the SOTASpotMonitor.exe file in your existing installation with the new one. You should now be able to see spots. I haven’t tested posting spots, but again, it should work.
