Well I think it would be too much to ask that a product be fully functional in every version of Poser, because some features weren't available in the past and the shader system changed.  They should specify what version of Poser the content will run optimally on.  Remember when Poser Figure Artist was out?  It essentially was Poser 4 with a new name and vendors were making texture maps for it and the newer version of Poser.  What one ended up with was runtimes full of Poser 4 texture maps that did not look optimal.  At least the "light" version of Poser is now Poser Debut--which is essentially Poser 8 Stripped of the other Poser rom except for the Pose and Render tabs.  I would expect that any new product that Daz has available in it's Poser section would work well with the latest version of Poser--if it didn't I'd be dissapointed.
