Some customized LISP commands not working in CAD2014

Hi,

I've been using AutoCAD2014 for a few weeks now and everything's ok. Suddenly, some commands in my LISP are not working, escpecially the complicated ones or the ones with formulas, like purge-auto save for example. All other customized commands, like shortcut for Refedit for example, are working.

I've also tried opening ACAD2012 again, only to find out that the same problem occured in 2012. (i never experienced this in ACAD2012.

I've done 'demandload' and restarted but to no avail.

Does anyone know what happened and how to solve it, please? :)

Thanks.
