Just about point 3: - The ONLY software I know having so many bugs leading to constant crashes is Vue Pro. This is - not only for me - a simple FACT. And I'm sad about it because I was so happy with Vue "standard" and happy with the features "Pro" should have. (Yes, I've installed "something else"...) - Then, no, there is no "possibility of asking for a refund", at least "here", in France (imagine I have now a working serial! :-( ) - Sure Poser 5 stopped crashing, as Curious Labs changed their protection system after release 2 (if I remember well). It's written on their home page. Maybe one day e-on will understand it's better to have the people who bought their app be happy than no one at all. (I know of ONE person for whom it DOES NOT crash! ONE.) - You can test the Vue Pro demo as much as you want, it does NOT use the same protection (e-on answer to my question about it, don't remember the guy's name, sorry). So, eventually, it won't crash. As the demos works eventually fine, you'll buy the "retail" version. And this one crashes. See? (Latest upgrade 4.53 270045 included)(yes, it's a beta, so what?) Regards (Sorry for my english, and no offence meant; those are just FACTs...) T J
