I had to uninstall/reinstall FS2004 however it was not a complete uninstall. I did not delete any saved files.Now, when I go to program the FMC on the 737, I get the message, "Not found in database" when entering in airport and waypoints.Do I need to completely uninstall the PMDG 737 and then reinstall it?What am I missing?Thank you!Mike

There is no such thing as a partial uninstall, if you uninstall FS then make sure to manually remove the FS9 main (WHOLE folder) through windows explorer and everything in it. Plus one cannot expect an add-on to work after uninstalling FS. The AIRAC is not a part of this sim per se, in other words, you need to download NAVAID stuff and install that for it to appear in the FS. What I would do? Try installing the latest Airac cycle and DELETE any previous saved PMDG senarios. If that fails then follow my first advice and start fresh.[h4]Randy J. Smith[/h4]

Had the same problem. Reinstalling the 737NG package will fix it. No need to uninstall.Gerry

Thanks for the help guys! Got it going again.

You're right Randy. I thought I by keeping my saved files, etc., that I would save time by not having to reload all my payware. It turns out I am having to reload it all anyway. Good advice;-)
