Anything else in your scene, especially hair? What texture are you using? Any other programs open at the same time? How long was Poser 'stalled' for before you closed it? How much space left on your scratch disk? Have you defragged recently? Installed any new programs? All appropriate memory patches installed? Does Task Manager show Poser hogging the cpu? Does Aiko render with a different texture? That should keep you going for a bit. The only 'problem' I've heard of about Aiko is from newbs who have not had to manually assign textures before and get caught out by her legs.
