"I have 512 MB RAM, about 6GB left on the HD and Windows ME." Do you really only have 6 GB left on the hard drive?! That's not much room when you're dealing with graphics. If that is indeed your free hard drive space, you need more room on the hard drive. I had used Poser 4 with Windows ME, and found it to be a most frustrating experience. Poser 4 still has lots of bugs and used to bring my computer to its knees at times. The best solution I found was to increase my memory to 512MB (the max my computer can handle), install Windows XP. I also installed Poser on its own 30GB hard drive, and strive to keep the maximum amount of free space for Poser to do its work.
