Obviously I'm not making it clear, that is a failing of mine I know!
Poser has a habit of saving everything in your runtime as compressed files with a "Z" on the end, so an obj file becomes an obz file etc.
The uncompress script decompresses them from obz back to obj etc.
It's this "Z" extension that "seems" to cause the problems I get most of the time but not all the time.
Others disagree with this and that's fine, I have no problem with that but it doesn't change the fact that it works for me and others [dlk30341] for example!!
Again if it doesn't for you, well that's unfortunate but at least you gave it a try which is all any of us can do with issues like this!

Injustice will be avenged.
