Thank you for responding!
I downloaded the program onto the new computer and imported the files with my plans. Everything in the plans transferred over (expect the materials don't show up now), but even with everything in the plans none of my bonus catalogs, purchased library catalogs and .skp files I uploaded into the program transferred over to show up in my library.
I tried updating my library, but I still only have the basic core. I'm fairly certain I will have to re-upload the .skp files - although it would be nice to mass load them from what I had versus having to do them individually - but I would think I should at least be able to access all of the bonus and purchased library catalogs without having to re-upload everything...
