what I do is copy my python folder elsewhere.  then when I get a new version of poser I merge the new python folder into it.  that will replace any old files with new but won't delete the old files, then I just replace the python folder in the SM poser folder with my almalgamated folder.

Then I find the preferences.  On a mac they are in application support, but may not be obvious until after you open poser, play and close it.

In application support the preferences for poser 10 include a folder with your old preferences from previous versions. I put back all the missing things and voila, back to normal well apart from the library unless you want to copy back that preference too.

One caviet.  Poser installer makes the permissions too strict on the mac, so before I do any of the above I make permissions for the poser pro folder to be read write for the folder and all the subfolders.

I aim to update it about once a month.  Oh, and it's free!
