EA is not compiling

 

hi, some years back, like 5yeaars or so, i hired a freelancer whom i coudnt reach to now,  and he made an ea for me, after these years, i tried to compile the file n its showing me error, is that normal perhaps mql5 upgrade or something?

thank you

 
Your EA probably needs some updating, you can post your requirements as a job in the Freelance section.
