Uh-Oh. Seems like you may have overwritten an original .obj file of the P4 man. Check the date of the file maleNudeHi.obj in your Poser tree. It should be 5/11/1998 something, so fairly old. If it is recent (like today or yesterday), then that is the problem. Check your Poser tree for recent files (like created last month) and note them down. You will need to recover those. If so, maybe best is to re-install Poser. To avoid to lose your work, backup your Runtime tree. Get the original files ( the ones you noted down) from the re-install and copy them over the backup-ed files. Last put the backup-ed Runtime dir back.
