So its doing it again. One of my addons is causing the issue. Not sure which one. The only addons I have are all the FSDT airports and GSX and the GSX expansion, all the FSX flightbeam airports, PMDG 737NGX, all the Captain Sim planes, Wilco 737 and airbus evolution vol 1 and 2, FSPassengers, ActiveSky 2016, and an addon that changes the textures of the ground at night. All these worked fine last month before I had to reset... did everything exactly the same... not sure what's wrong.
Edit: I'm an idiot. Didn't think to check the KCLT forum. Saw the post about sode. all fixed now.
