Hi mumblebox, what a coincidence, I was just on my way here to find out the same answer :) I've tried everything I know possible, and on some things I still get the i/o error. A while back someone suggested the "Grouper" program, and while I've used it successfully many times, on some obj's I still get the error. Does anyone have the correct solution for this?? I too and running Poser Pro Pack with all updates, and Bryce 5 with all updates. 1.4ghz, 768mb ram, so I dont think our problem is our systems. Thanks for any assistance you brycers out there :) Deb
