When I used Queue Manager with Poser 12.0.757 I got the following error message.  I reinstalled Poser & Queue Manager but the problem didn't go away. System: 
Windows 11 Pro
Intel  i5-11600 @ 2.80GHz
16 GB RAM
NVIDIA RTX2060 (Studio Driver 511.65)

Rendering normally or in the background works fine.  

I tried lodging a support ticket at posersoftware.com, but the support system doesn't seem to be working properly.

Any suggestions?
