I have Poser 6 and DAZ Studio in the moment. I also had Poser 7 installed but after SR1  no one of my Posers worked anymore. (I heared that this probleme is with german XP only). I re-installed poser 6 again and it works. I also re-installed poser7 without SR1 again, but it still couldn´t read anymore. So I have uninstalled Poser7 till a better SR will come.

If a new version works well, I only have this installed. I think I don´t get back to an older version again.
