I'm using V220.127.116.11_x64 and pointing the Active Sky folder in the config to C:\user\name\AppData\HiFi\AS_XP\Weather. P2ATC is reporting the weather as Clear, Winds light and variable QNH 0000 which I assume means that it thinks something is available but not reading it correctly. I am also pointing LittleNavMap weather to the same folder for ASXP and it shows the correct weather matching ASXP.
In the log file I see these errors:
Error in XPWeather DecodMETARString 02/02/2019 21:44:23
