This is really driving me crazy. At last I got Maya 6.0, and Mental Ray, but everytime I try to render with Mental Ray the whole *@$!- thing crash. And always with the sane error message in the output window

.PAR 0.0 error 021310: no connection to 0
PAR 0.0 error 021018: msg send to 0 failed

using a FX5700 card

Does anyone know what to do
