Steve, it sounds like you're deleting libraries and things you don't need. I wonder if that is part of the problem. Also, if you have Poser 4, all your stuff should only be in the main Poser Runtime. So maybe I misinterpreted your statement about Runtimes all over the place? You might consider running CorrectReference (free) to see if that will help your problem. There is a chance your Poser installation is so mixed up that only CorrectReference Pro (CRPro) can help fix the problem. If so, you can find it here in the Marketplace.
