Problem Adding New Airport (Weather)

I purchased FSrealWXv2 and, after installation, discovered that it works fine at a variety of airports, but not at my own custom airport near station CWSQ. This is being used with FS2004. I have FSUIPC version 3.9.9.9 installed (and registered). When setting up FSrealWX the interface options were adjusted (e.g., checking for FS weather stations and generating a new airportlist.txt). With FS2004 open, upon clicking the Download WX button a message displays "no metar station in vicinity". With the program window open, the "Set ICAO WX" button changes to display the next-nearest airport (which is CYSY), however remains greyed-out. Typing CWSQ into the Metar box brings up the station's weather but reads "no metar found for CWSQ" in the program window. I've checked the airportlist.txt file and found it contains data for my airport. I also tried creating airportaddlist.txt and icaos.txt files and adding these into the FSrealWX root folder, without success. The data for this airport is as below,

CWSQ;Aulvik National Park;Canada;104;74.1333;-119.983;1;1;0;0;1

Many thanks for any suggestions/assistance.

Thank you for looking into it, I can get weather updates at nearby airports at least. Cheers -
