DIFFUSE file in folder of example

Hi all
I want to run the DIFFUSE file which is one of the example codes in lammps documents. But when I run it, it gives this error:
lammps-users at lists.sourceforge.net
Also II am using the lates version of lammps but this example is from previous version. This file is among the list of changed files!!
So how can I run this code??
