You may have installed the wrong one. There was a recent update which I think was a separate zip. If you have Poser 8/Pro 2010 you don't want to apply that extra zip. If you have Poser 9/Pro 2012 you DO want to apply it. Things changed in Poser's implementation of Python between the last two versions.

Now, that's as I remember it. Does not mean that's how it was...LOL. Your best bet is to contact RDNA ;).
