This was the address in the readme.  predator-2000@gmx.net

But as you can see above it was from 2001.  I'd be surprised if it still is seeing as this person has apparently made a point of erasing his traces from Renderosity.   Can't say I remember anything about what happened with Nadya/Oxana.

I guess I'm not as much a historian as I am well-organized in backups ;)
