Now for the boring questions.... which version of blendigo do you have installed? Which version(s) (if any) of python do you have installed? Which release of blender are you using (official 64bit 2.49b?) ?
Using blendigo 2.4.10 now. All I've done is upgrade blendigo.
Most likely installed blender 2.49b 32 bit in C:\Program Files\Blender Foundation\Blender then overwrote with the 64 bit files since there is no installer for it.
Python 2.6.1 64 bit.
Win 7 ultimate 64 bit.
Compiled with Python version 2.6.1.
Checking for installed Python... got it!

Talking about particles... why won't they emit light? Group visualization. Only the source object emits light. Particles render with the same material but without light emission.
