Do you mean PMDG don't initialize the panel state and everything is dark and you can't do anything even with the FMC ? I have that problem right now with the Delta liveries from PMDG site.I saved my flight, which saved the panel state (I can see the file and can reload it without any problems if I don't end the actual flight from FSX. But If I close everything, start FSC and load the lfight, the panel state don'T initilize at all, no countdown. Will try with the SOuthwest livery whre I know I had it working before. But one thing I was not using at that time is RC4. Need to test more before being sure of this.
