xrun: *E,FILEMIS: Cannot find the provided file ./netlist.vams

First, I am *very* new to Virtuoso, please be gentle!  Something isn't right with Xcelium simulations.

I am working through sanity testing the simulator.  I have a simple schematic cell view that I created with an analogLib.VDC, my own inverter, and a ahdlLib.resistor.  I also added supplies vdd and gnd.  I created a config cell view:   VDC is using the spectre view, res is using veriloga, my inverter is using behaviorial, and the test is contained in a schematic view.  I used the "AMS" template to for the cell view.   From there I launch either ADE Explorer or ADE L (the end results are the same).  I'll describe the ADE Explorer path. 

I selected the ams simulator, with a transient analysis, using the Spectre solver.  Using the "AMS Unified Netlister with xrun" option, the system fails to create a netlist (results follow), but using the  "Cellview-based" netlist option, the netlist generates and the simulation works exactly as expected.  Because I am new to the tools, I cannot tell if the problem is in the interface between chair and keyboard  or if its an installation issue or something else.

What I believe are relevant entries from netlist.log:

Finally, the simulation terminates with xrun.log:

xrun: *E,FILEMIS: Cannot find the provided file ./netlist.vams

However, Changing only the "Netlist and Run Options" to use the "Cellview-based" the simulation works exactly as expected.

Nothing appears to be segfaulting, and nothing else looks out of place.
