I'm on Win XP 32-bit Service pack 3.  My graphics card is a GeForce 9800GTX/9800GTX+ with the latest drivers.   I'm running Poser Pro 2012 with service release 3.1 and even DSON works without a hitch so I know I'm on the latest SR.   Could DSON be causing the problem?  I don't know if any python scripts start automatically.  How can I find that out? 

And here's what the octaneplugin.log says.   Towards the end is says Octane library failed to load but I don't know enough to understand at what point that happens and for what reason:
