I upgraded to the latest version of GT a couple days ago, and I get a CTD right after I spawn at any airport. If I remove the GT plugin, I have no issues. Anyone have any ideas on what to check.
Your best bet would be to contact Just Flight support. They can get a proper dump file off you and see what may be causing the issue.
NB - make sure all your other addons (they call them 'plugins' at X-Plane) are up to date.
