After installation of Mavericks, I get the warning : Apple Qmaster File Agent not found. Any solutions?

Question

Hello,
Everything was great running Mavericks in FCPX and seemingly Compressor... up until I hit the 'submit' button on a project.  I found the following thread, which is related, but it doesn't mention Mavericks so I started a new one here.  I'm guessing my problem has to do with Mavericks because I was able to export videos fine yesterday before the upgrade.   I followed Russ' potential solution in that thread to no avail.  The same problem happens whether I try to use the systems cluster or not.  Here's the thread:
https://discussions.apple.com/message/23434754#23434754
After trying all of that, I decided to use FCS Remover to remove FCPX, Compressor and QMaster (like I've had to do in the past when something would stop working after an update).  I then re-installed everything and opened my Compressor project back up for export.  I was expecting it to go through at that point, but alas, the same dreaded warning message appears:  "An internal error occurred: Apple Qmaster File Agent not found."
I'm stumped.  Don't know what to do besides uninstalling all my pro apps, including QMaster, and reinstalling.
Any ideas?

I set QMaster Preferences for Compressor Services to "Share" = checked and "Managed" = Checked, then I set Instances to 4, it did not work, back to the original error "Qmaster file Agent not found".
Look at some of your information I noticed that in Qmaster Preference the "Advanced" - Network - Use Network Interface: "All Interfaces". So I changed that to "Built-in Ethernet 2" (NIC my cable is plugged into) and set "Enable Port Range: From 50,000 with number of ports 1000".
So, for the heck of it I tried setting Instances to 2 -- and it worked, look in Batch Monitor I see 5 segments, 1 audio and 4 video with 2 out of 4 video transcoding (each was assigned about a 2 min chunk of video). Progress -- ok, so now I set Instances to 3 and submit batch -- it's still working, I get 7 segments 6 video and 1 audio. Ok the big test, setting Instances to 4 and it still works!! 9 segments, 8 video and 1 audio, WoooHoo, its working!
Just to be sure I open up Activity monitor and all 4 of my CPUs were cranking at 95% utilization.
Also checked OS X firewall setting, they are set to most minimal. Checked my router also, 192.168.1.2 is the IP assigned to my MacPro and the router is set to DMZ that specific IP (meaning is basically open to any port).
But I think the KEY in my case was to change the "Use Network Interface" from "All Interfaces" to "Built-in Ethernet 2" and then Enable Port Range from 50,000.
On a side note, the progress bars in Batch Monitor and in Compressor are way off with the "Remaining" time estimates -- overall progress will suddenly jump -- it looks as if the remaining time isn't being divided by the number segments currently running or something?
Thank you for your assistance.
