Same issue when I was trying to make a flight on VHHH/YBBN. However, I made a successful flight on WSSS/VTSP. I have installed YBBN and VTSP addons by Orbx, and VHHH addon by WFSS.
Update.
I made a experiment. If Dep/Arr contains YBBN, it will CTD. However, I tried WSSS, VHHH, VHHX, ZSPD, ZBAD, ZSHC, ZPPP,YMML,NZAA and other many airports, they works normally. It might be some problems on Navigation data or something else related to YBBN airport. I thought it might be caused by their new runway. However, VHHH also have got a new runway but no CTDs. Perhaps you can try changing both of your origin and destination airport and make a try.
