I have been using the free version of Draftsight for a few months, I am considering purchasing the professional version.

I am an experienced AutoCAD & AutoCAD Map user, recently retired. I have several lisp routines that I used with AutoCAD but they do not work with the trial version of Draftsight Pro.

I get this error message: xxxxx.lsp cannot be loaded, because it uses a wrong DLL version. Current software host version version is _3.09_11.

Can anyone let me know what is required to load these files?

Thank you
