Well I am using Poser 7 and my machine is 64 Bit. I was considering upgrading to Poser Pro 2010 because I hear Poser 9 isn't 64 Capitable either. The thing is, I have this room that uses about 6 Million of the memory and then that message will show up on me. So you guys recommend that I upgrade or what?  Because I am planning on it. I can't afford Pro 2012...Its way too expensive right now. But Poser Pro 2010 seems just as good as Pro 2012.
