Hey Roman, tnx for getting back to me. I checked globals but everything is ok. Is it connected to the message I get when i start Maya, "Could not create command port" ??? Any body have a clue?

Hey.. When I attempt to do a batch render in Maya of a file sequence I get the message Error: Cannot find available port. I never had this in PLE. Have I set up something wrong??
Please help
Orlan

I recently bought Maya 4.5 and also downloaded Mental Ray 1.5 Beta from AW's site. It is installed as required in the right directory but crashes the program when I load it up from the Plug-In...
