from what I read from kupa...SR2.1 will REMOVE the security protection from the current install....or will we have to reinstall.... And also, I would presume that we would need to install the patch prior to actually running Poser 5, otherwise the dreaded copyprotection thing would popup asking for authorization codes and stuff.
