Well, I've found using Wardrobe Wizard that sometime THAT program has trouble finding geometry, and it's usually something as simple as a space being placed BEFORE the path statement in the cr2.  Sometimes it's little things like that are hard to spot.  And I do have old scene files that I have trouble loading because they were written before I developed the runtimes I'm using now.  But I rarely, rarely, have trouble loading items out of the library and I use Deep Search.

Freestuff being freestuff, if it's something I really I want to play with I'll go through and look at all the path statements.  Otherwise I shrug and delete.

I wonder if we could test something the OP is having trouble with.  Something Basicwiz has downloaded and is having trouble with. 

As for my own humble give-aways ... yea, everyone makes mistakes.  On the flip side, everything on my site comes with a full money-back guarentee, and are usually worth every penny you spend for them ;).
