Lunchbox & other BakeAttrib obj's not working SR9+GH9.0006

None of the methods for Baking Attributes works on my configuration.  (I'm also on winXP Sp3 32 bit if that matters; hopefully not.)  Lunchbox Object Bake makes layers, but nothing's on them.  The BakeAttributes2 (posted in another forum on sub-layers) also doesn't work; stays red with undiscernable script error "1. Error: 'Rhino.DocObjects.Tables.LayerTable' does not contain a definition for 'FindByFullPath' (line 127)"

[I searched for older GH versions but only found thread pointing to an archive "under maintenance."  Funny, I normally keep everything, but this is one case where I thought, "the internet will always have this floating around..."]

Any suggestions?
