Render Queued

I would like to purchase three single licenses for a small render farm, but in testing the software, I am unable to render a Maya scene file. The file is queued, but will not start. Here are the exact specs of what I am trying to do.

• Muster 5

• Render was set up as ‘Maya to MR’

• Scene file included a Polygon sphere on polygon plane

• Mental Ray renderer was selected in Maya’s render globals.

• Three Intel Core 2 Duo Vista machines, each with a copy of Maya 2008 Unlimited

• All machines were recognized by Muster Explorer, and the Maya job details show up on each machine

• No external textures

• Scene file was recognized, the correct path to the file was being used, on a NAS networked drive shared by all three machines

• Muster was run using the application process on each machine rather than windows services

Please let me know if there’s anything that can be done, or a step that I am missing. I am very anxious to purchase the software as the interface is intuitive, and the software package is getting great reviews.
