There are a few recent threads with people having whatpulse crashing and unable to start.
I had that problem too, the logs indicated that GeoIP.dat could not be openened. I looked it was a 0 byte file.
Solution:
Download GeoIP.dat
(i used this website: https://mailfud.org/geoip-legacy )
Put the new GeoIP.dat into this folder replacing the old one C:\Users\***\AppData\Local\whatpulse\
Whatpulse is running fine again
