Im getting the same issue with 11.10. The crazy thing is that the log file doesn't give a reason why.... It just says the application crashed.
Im having the exact same problem, one night I did a small flight and then turned off my computer but had to update windows on my laptop. so I did, and when I went to play later the next day my game crashed as soon as i started the game up. (this was in the last x-plane update) ill attach the log.txt file if you wanna take a look at it. some help would be awesome.
