Quote - Does it work for you PerfectN? I saved a V4 scene yesterday and today I experience I cannot open it. Crashes to desktop everytime. also unchecking Use external binary morph targets does not help.

Any info when V4 will work correctly with Poser 7?

If you've saved a scene with V4 in and you had binary morphs turned on, you'll need to delete the PMD file before the scene will load (the option just dictates whether binary morphs are saved, it has no affect on loading).
You will lose the morphs by doing this, but it will allow you to recover most of the scene.
