I got poser 8 working now. 

While Putting Poser8 through it's paces,  I can't get my other Runtimes when I run my search. Nothing happens at all. All I get is Poser 8s Runtimes. I search for a figure, and I search for and for a Runtimes. I seached like you have for Rutime V4,  Runtime, or efrontier Runtime. Poser 8 just sits there laughing at me. Sayin, Ya big dummy, your pushin where you should be pullin.  There is no seaching being done! I can open any of my Poser 8 files, Hair, props and such.
