I have Poser 4.03 and the ProPack with the lastest Service Update. I also have Vue4 with the 4.01 patch. I have the 4.02b patch as well, but I haven't installed it yet. I wanted to see what others said about it before I took the plunge, as 4.02 had problems. Anyway, I installed Poser first and then Vue, which I got later. I have never seen the error mentioned above. But I think I import my models by the method droyd mentioned above. I click on an icon on the left side of the screen about midway down. It opens a dialogbox with some models displayed in the middle. At the bottom are three buttons. I choose the one that says file and then I browse to the location where my pz3 file is. I've never had any problem with this. And if there's another way to bring a pz3 file in, I guess I didn't know it. Hope this method helps. Kevin
