Hi,
I have just uploaded Updated Versions 7.1.1 Full and Light. These two versions are more usable and easier to import in your own blend files. Groups have been modified to avoid importing unwanted objects due to the fact that Blender sometimes appends some object not belonging to selected groups, but linked by Parents or Constraints.
The constraints have been simplified and the manual in the text window has been improved and contains many useful informations.
Same page, but updated files :
