Need help modifying a code to include Automatic Expiration

Please , i am just learning to write mql language from the basics. i dont really know much for now.
i am trying to add code to some indicators so that it will expire automatically after 30days or 45 days of trial without me , interferring it all the time. this means any time it is being used, after 30 days (or 45 days,) it automatically expire and shows pop up alert like ' THE INDICATOR HAS EXPIRED, CONTACT [email protected] FOR FURTHER ASSISTANCE", just in a simple and easy way to protect it
but it is not just working and compliling as i have been doing it.
PLEASE CAN SOME ONE JUST ASSIST ME IN ITS SIMPLEST FORM,
1.THE CODE I WILL COPY AND PASTE ACCORDING TO WHAT I EXPLAINED
2. WHERE TO INSERT IT (ATTACHED IS 2 DIFFRENT INDICATORS SO THAT IT CAN BE OF HELP BY SHOWING the inserted codes IN DIFFRENT COLORS SO THAT I CAN GET IT ONCE AND FOR ALL.
I WILL REALLY APPRECIATE IT IF I GET ASSISTANCE,MATES

please what should i change it to, i just need help. Is not working. Can you just help me with the code and what line to insert it. Thanks

oh no. Nobody is helping me, not happy

Why not ask the author(s) of the indicator(s) you want to protect for help as it looks like a commercial endeavor.

Tips:

ALL CAPS is tedious to read and considered shouting on the Internets.

Post code in code tags for improved readability and to prevent the editor from removing characters from the code.
