Hi Dan
My problem is strange.
I followed your instruction to delete the ARPT_RWY.dat and restart the window and FSX. The PMDG 777 display panels are dark and PMDG 777 doesn't kick start its initial setup. I have done this again after i re-install the FSX and PMDG and the second attempt has the same problem.
I still cannot find out the problem whether it is the NAVDATA cycle 1501 or whatever earlier, or the ARPT_RWY.dat

I hit the same problem with NAV DATA AIRAC-1413 on PMDG 777 I found the following airports with runway error with its messages CYVR: CYR ERR:13 RWY N/A CYYC: CYYC ERR: 17L RWY N/A KORD: KORD ERR:10C RWY N/A
Just want to share with the community of my take off which the PFD, ND, Autopilot buttom were freezing while the pop-up PFD was working normal.
I suspect it was caused by changing view from Virtual Cockpit to outside view and return back to VC
