Submitting Shake Script into QMaster

The QMaster tool appears very simple on the surface, however, when I add a Shake script, it opens up Batch Monitor and sits there forever saying "Processing: Preprocessing". I've left it that way for hours and nothing seems to be happening. Activity monitor shows nothing. When I render from Shake, all 8 cores are screaming. I only have one fileout node in the script. Maybe I am missing something incredibly easy. I have tried this on 5 computers now, all 8 cores. I have submitted them to the local cluster and to other clusters, but to no avail. I have tried this several times in several ways.

Am I missing something here? I must be. We are on XSan, but I can't imagine anything is wrong with that. I disabled the UNC (Universal Naming Convention). I've searched manuals over and over and have been on more forums than I can remember. Anyone understand what I may be doing wrong?

-thanks.
