Your LDRAW parts installation seems to be incomplete.
The folder "8" normally is located inside the "P" folder, where the missing file should reside.
You should maybe re-download the most recent complete collection of official parts (complete.zip) from
http://www.ldraw.org/downloads-2/downloads.html
and re-install that.
