PMDG users. I am familiar with how to use the 737NG FDC. The problem is, every time I try to initialize with an airport id, I keep getting a not in database error message. I am using common airports like KBWI, KOMA, KSMP, KSTL, and none of these are recognized. Do I have to download these and if so, where do I install? I read the instructions on how to download STARS but no luck. I am getting really tired of flying VOR airways!!!
BTW, I realize this is operator error.
I broke down and uninstalled both FS9 and PMDG. After reinstallation, everything is working fine.
