I have been running the Institute questline and *SPOILER ALERT* I am at the point where I have to go to the airport to destroy the Prydwen. I am able to relay in just fine, but after a small but non-specific number of seconds, the game crashes to the desktop. No error message, no freeze up, just black screen for maybe half a second and then gone. What should I do?

Running Windows 8 w/ up to date Nvidia drivers. THE SPECS ARE MET.

EDIT: It also seems to be related to going towards the parking garage/Boston Airport Settlement
