Lisp not working anymore in AutocadLT

[rdellorcoVW4WC]

Hi,
I've been using a LISP called Layer Director by Mac Lee (http://www.lee-mac.com/layerdirector.html) on Autocad LT.
It worked for few weeks and some days ago stopped working [error when using one of the command present in layerdirectordata: bad argument type: (or stringp symbolp): nil].
I don't know how this is possible, i'm quite new to autolisp.
Do you know if there is a workaround or a debug method?

Thank you

Is the problem limited to just one single DWG file? or ALL of your files everywhere?

It's working fine here in LT2024.1 in all of my files.

Re-download the original version and run it, is it good or not? If yes, post YOUR version to take a look.

I've already tried that, downloading the original version, because I
supposed that I've made some bad editing of the file.
Unfortunately, on a new drawing, with only LayerDirector uploaded, I
have the error message and the lisp is not working as it is supposed to.

Ok, then you can try an alternative...

Most likely your edited version is still running: curious why you never mentioned that you edited the file in your first post. Why not post that here too while you try to ONLY load the clean versions downloaded from the website.

Here you are the edited version, if it can help.
So, how should I clear all uploaded lisps?

It's a bit messy... but nothing wrong with the file.
