The save as vob and reload it then does not help neccessarily. The Poser connection may still be there. Try it out first. I say "may" because i am on Mac and it could be different in the two versions. Of course, if a vue-file is corrupted it will not reload again - whatever update you use. A corrupted file is bad luck and happened before with all Vue versions from time to time. Depending what happened when you saved the original file. For example when Vue was in an unstable situation already because an error accured - maybe one that you haven't noticed but happened. Or a crash in the middle of saving. I had that as well before.
