Greetings.
I can reproduce this bug 100% of the time, which unfortunately for me, makes the A310 unflyable.
Basically, right after I enter the departure and destination into the INIT page, as soon as I hit the button on the MCDU, I crash to desktop instantly.
I've provided a video which shows step by step.
Let me know if there are any logs which can be helpful and where to find them.
The only things in my community folder besides some add on planes (PMDG, Fenix, etc) and scenery is: GSX, fsltl and FSrealistic. I have not installed the A310 enhanced package.
