Hello,
I'm trying to calculate PET, and for that i created a text file containing:
date,time,air temperature,relative humidity,wind velocity and the mean radiant temperature.
the first problem i faced after the input of the data file and clicking New, was this message "Read error from datafile!(Date format?Number of columns?)", but after going through this forum I changed the "tab" separator in the text file to ";". Now I'm not getting this message but instead the software just stop working (freezes).

what I have already tried is:
-running it as administrator
-reducing the size of the data to just 4 rows of measurements
-test it on another laptop
-ensure that there is no blank spaces within the text file

Till now I can't figure out what might be the problem, so your reply to this message would be highly appreciated
Thank you in advance for your time.

P.S.Sample of my data
