Hi Barry, I have already tried security update and also contacted local technical support and they are trying to solve the issue now but still with no success. I sent LMT logs to them so they can contact Graphisoft directly with this problem.

This is the problem, but connection to internet is normal and also logged in to graphisoft ID.

Hello,I have a problem with license / LMT connection. Archicad 27 is working normally, LMT cannot establish connection to the server. After installing Archicad 28 it doesn't work - cannot find license. What could be sollution to this issue? Thank you...

I really hoped Archicad 28 could count % of areas with new update!  Without need of learning to code in Python 

I also agree, I am struggling with writing my first script and would like to learn how to but cannot find any learning path and trying trial-error way,unfortunately it's painful and not working
