Same thing here. I tried one of the scene preset (falling ring) and it worked at first but gave me that same message after 8 frames and stopped working... Also if I pause the rendering I get the rolling ball and I have to force quit Carrara I can connect without a problem with my network computers with EIAS Renderama ,Strata RenderPro and C4D 9 network. When I tried Transposer 1 on the network rendering a while back, it didn't work and was told by eovia at the time that transposer 1 was not compatible with the network rendering. I got the upgrade to Transposer 2 that is network enabled and it still doesn't work. The problem hopefully lies with the rendernode itself. One of the main reason I upgraded to C4 was for the network feature so I really hope I can solve this This is a mac to mac network Jean-Luc
