I picked up the -400 and -500 in the recent flash sale and went to go fly around in the -500 but when I click fly now, the sim just closes without any error on screen. But I get this error log in the event viewer. I first tried using a Southwest livery installed via ACE, but the default livery also causes a crash.

The -400 works just fine.
