I removed FS9 and installed FSX, I missed my PMDG 737NG so much I re-installed FS9. Tryed to install FSIIN but crashed FS9. Unistalled both and did a clean FS9 install. PMDG 737 aircraft are still there and I didnt reinstall them???? Everything works fine on 737 except when I program the FMC it does not seem to have an airport database. If I enter KDAL for example I get a NOT IN DATA BASE message in the scratch pad. Any Ideas, ThanksAndrew Williams

You would seem to have a fragmented installation as parts have been deleted and others are still there. Get the removal tool from http://www.precisionmanuals.com/file_libra..._737_REMOVE.EXE and uninstall the 737 then reinstall it. You should be fine then. You may want to download the last fully workable airac and sidstars from avsim. Search for Richard Stefan.

Thanks, I'll try that. Andrew

OK..For any others out there who find there FMC data base messed up (Missing procedures, error runway not in data base, etc.) You must purchase the new AIRAC for 2007 then install the 2007 SID/STAR navpac. The AIRAC is $13.00 US. My problem was I had the 2005 AIRAC and the 2007 SID/STAR. Your current AIRAC version can be found on your INT page the FMC.
