finalRender distribute rendering problem

Each time I try to render in distributed mode I get this:

3DS Max and FinalRender installation on both machines are the same, the scene is shared on a network drive and tested on both machines (this is simple test scene, it renders with no issues) but always get this nasty error!

Interesting, I can do distribute render with Vray with no problem.

3DS Max Design 2013 and finalRender from Nomad.

Any idea???
