I just came very close to losing All my Poser work that I have done this year. After another Poser 5 total lockup/Hard reboot, I get a message that my registry is corrupt (Corrupted hive). Unfortunately I hadn't backed up in several months... (DOH!) Fortunately after a lot of Skull sweat, and patience I was able to recover all my data intact (knock on wood). I will never go more than a week without a backup again. ^_^
