if it's happening to all the pz3's it the system rsr thats broken- poser uses 2 types of rsr- the libary one that can be deleted and the system one that is part of the program itself. Do this- it's real simple- copy you runtime out to a safe place delete and reinstall poser then just copy you old runtime back in :) poser tends to accumilate errors during crashes and just plain over time. this is the simpelest and most direct fix for most problems- also makes poser run a touch faster to do this sometimes :) it's a good idea to reinstall this way every now and then just for maintaince :)
