Just a couple more thoughts while they are fresh. I backed up my preferences before I did the uninstall / reinstall. I also selected the option to remove existing preference files, as recommended in the message above that option. The reason is because I was changing the location of my "Poser 11 Content" folder. I changed it from the root of E: drive to a subfolder - E:\PoserRuntimes\Poser11Content. Notice I removed the spaces between the words. I do that out of habit when I name folders since embedded spaces require special handling in a lot of apps.
