I'm glad some of you think spending $200 here and $200 there is cheap....clearly you have a different economic base than I do, and I'm pleased for you. I wish I had that kind of money. The fact is that I took my hard drive to be be checked (and have the memory expanded) before I installed Poser 5, because I wanted my system to be working as well as it could when I got the software. If my operating system is now in dire need of repair, it's because of damage done trying to get Poser 5 to work. I don't have the technical expertise some of you have. I didn't start out thinking I was going to have to rebuild an entire computer system to get Poser 5 to work, and my modest opinion is that I shouldn't have to. I'm not a prefessional graphic artist...I will never recoup the money I've already lost in this venture. But it does puzzle me why people are having such varying experiences with Poser 5. Some people are sailing through the whole process and and some of those are thinking those of us with problems are idiots. I doubt if I did anything different with my installation than anyone else, and it is extremely unlikely that I have some peculiar software set up that causes Poser 5 to crash. I think Poser 5 really wants its own computer with nothing else on it. Well, I can't afford that. Oh well. It was, for me, an expensive lesson learned.
