Hi, New to Aperture and ApertureExpert.

I am trying to rename (I screwed up) 100 or so files that were imported using  Joseph’s naming technique.  I go to Metadata  - Batch Change – select Version Name Format – select my custom file name format – Select apply to orginal.  It does not change the name but adds to what already was there.   I tried a 2nd time and now my file name is actually 3 names.  HELP
