Oh well..that's super strange why it isn't working then. This window appeared when I first tried to load this lisp and I did click on "load" too. So why doesn't it work?

Do you think the problem might be my Autocad Version? I have the one for educational purposes (2019).

Or maybe my settings? I'll attach some files for you.

This is error message in my command box:

Here are some of my settings:

I also added the path of my lisp file to the support file path after it didn't work. Many people suggested to do so but still it won't work. I don't even know if it's necessary?

Could you tell me which version (2017,2018,2019) you have used to try this file so I can download it?
