I honestly don't understand why some computers have issues and some don't. I built my own computer 4 years ago for more power to use my 3d programs and I don't have problems with it. I bought the program directly from VWD before it was on sale here. It wasn't a secret. He made it clear that he would sell it privately. I cut my teeth in 3d in Poser 4 in 2000 but now prefer DS now. I bought the Poser version to play with it in Poser. It works great! I have chosen to wait for the DS version instead of buying privately. Kittycat, I don't know what the problem is but I don't think its the program. You admitted that you have a strange computer configuration so to blame the program for not working isn't fair. Others aren't having issues. I don't have issues with Poser. I have the newest version and it works like a charm. Poser is unstable on your computer so you can't use it. The common denominator here is your computer. It definitely has issues. I am glad the developers were kind enough to give you your money back for a program that doesn't work with your computer but I think, in all fairness, the issue here was not the program.
