I use the latest dev version and have no issues at all, no CTDs at least and all flyable. just did a night flight from KATL to KJFK with no problems (except that fuel load is not imported from Simbrief using the MCDs ATSU menu). If anything fails you may want to complete delete your FBW installation and download all again since the installer only updates increments and you may have something odd on your HDD/SDD
