I've never experienced scene corruption. Which is really saying something considering how much morphing I do. I mean seriously. Scene corruption is a thing from looong ago, like Poser 7. The bugs were ironed out since then. Boni is correct though, save yourself some headaches and reinstall V4 and her packages. Dont forget to run the bat file.

As an aside lakes123, didn't you have a similar problem with gen4 figures a few months ago?
