Okay. The next thing I can suggest is reinstalling both, after saving your P4 runtime elsewhere to copy back into the new install, and likewise with Vue. But after uninstalling them, do a search in the windows tree for anything that has 'Vue' or 'Poser' in it. Registration tag files tend to get stuck into out of the way places, so that they aren't easy to find and copy. It's a anti-warez trick. You might also want to go into regedit (only if you are comfortable doing so; otherwise, get a geek to help), and search the entire registry tree for anything regarding vue and poser, and deleting any keys you find there. Your problem sounds like a corrupted linkage through your OS, and about the only way to get that fixed easily is to hunt out all of the linkages, delete them from the registry, -then- reinstall your applications. That way, so far as the operating system is concerned, these are new installs. If there is any garbage left when you uninstall them, the OS will treat a new install as a re-install, and link whatever is there into the reload, giving you your problem right back.
