It seems you exited from the sim too quickly.
Could you try do it again and wait a little bit ? If you are parked with engines off and parking brakes on, wait until AFTER you see the GSX Traffic Cones appear around the airplane ( assuming you are not using an airplane that has them disabled ). Also, try to use GSX, so you can see the error message about no parkings and THEN, exit the sim, so the Log would hopefully contain something more meaningful.
The only thing "unusual" in your log, is the GSX started to create the MODEL cache, which is required to do when new models have been added, but it didn't finished but, it's difficult to say for sure, not knowing if your log was just cut out because you quit the sim too quickly.
