First, big thanks to egleaves for uploading these pipe fittings, saved me a ton of work.

I downloaded the aformentioned template file and lookup tables, and copied the csv files to the appropriate folder on our server (I:\BIM\Revit\2012\LookupTables). I checked the revit.ini file to make sure everything was pointing to the right file location, and confirmed that it was.
I started testing the fittings in the template file, and they came in broken (see attached). I tried everything I could think of to fix the fittings, and eventually copied the lookup tables back into my local hard drive (default Revit Lookup Table location). They worked. My question is why. My .ini file is still looking at the I drive location, why oh why would copying the lookup tables back to my C drive cause them to suddenly work?
I need a beer.
