I had version 3.20 on my old Windows 10 laptop and I recently installed version 2021_3.32 on a new Windows 11 laptop.
On both computers I experience the same issue. I can open the Sounding display window normally (through Data-->Sounding), but when I enter either a WMO or ICAO code or select a station in the available list, I get an error message. This message tells me that the file was not found. As soon as I get this error message, Digital Atmosphere hangs and I must restart the application to be able to use any command in it again.

I assume that this is caused by a bug. Are there any solutions for this issue out there?
