Some information might help us understand: 1.) What is your operating system? 2.) Have you checked to make sure you have the latest Service Pack for the ProPack? There is one. 3.) Have you defragged your hard drive recently? Run Scandisk? 4.) Have you tried rebooting? 5.) Is your Poser installation on the same hard drive as your operating system and other software? I moved Poser over to its own 30GB hard drive and it helped tremendously. 6.) Do you have all the latest updates for your hardware, software and operating system? *** Believe me these questions are relevant because they'll help people nail down the facts, and possible causes or solutions.
