Just as a follow up...I have been able to render animations without this problem as long as I don't render with the audio and add it in afterwords...

But now I have a issue when rendering some scenes, not all, where I get a "the poser executible file has stopped working" error and I lose the entire thing. Sometimes it happens 10 frames into the animation, sometimes it happens 100 frames in. 

I have tried re-installing and I am running SR2. I have tried increasing virtual memory, I have even tried rendering half the frames then going back to render the second half at a later time, this still happens. 

Any ideas? :) thanks in advance.
