if you're using high res textures and bump maps and shadows and all the other rendering goodies, it can still run out of memory with 512....try rendering it smaller or with less stuff to see if it turns out all black again. And make sure that the volume (partition) with poser on it has enough space--if you have 100 gig but only 1 of it is free on poser's partition it'll have trouble. You can try increasing how much of your hard drive is given over to virtual memory/swap, win2k starts kinda low on that setting. MaryCanary
