RPI 4 - install and info required

Hi again brian
Ok so i followed this info

now when i run i get looking for file /home/pi/consolewdfiles/outdata.txt
I created that text file and make it access / edit by anyone and restarted it and it still says the same.
My using is WMR300 if ive not mentioned before. Am i supposed to install a driver for it? if so where / how.
I appreciate your help.
