This applies to WWL 7.2.225 on multiple computers running Windows 10x64 Pro Build 19041.450, Insider Build 19207.0000, and Build 190420.450. All systems have Kaspersky Internet Security V21.1.15.500(a). My zip code is 25177 in WV.
For the past several days, WWL is no longer able to find weather stations in my area. It can find the WeatherBug station at nearby zip code 25302, Yeager airport.
I am having the same issue on Windows XP, with Kaspersky. Did it once before, and a reboot helped. Happened about 2 weeks ago. Only Weatherbug stations show up in the station search. Did a reinstall, with no change. The non-Weatherbug stations no longer show up, and I have been using one in our city, since it would be the most accurate.
