I have not been able to install MY ai flight plans after installing FS9update. No problem with ProjectAI flight plans. I am using Ttools2.0. WindowsXP.Has any one else had this problem? rnails

How are you trying to install your flight plans? Are you using a separate trafficxxxx.bgl or trying to combine your flightplans into the default traffic030528.bgl or some other available trafficxxxx.bgl?Nothing was changed in the trafficxxxx.bgl file structure that would preclude you from adding additional flightplans.W.

I have tried editing traffic030528, traffic_PAI, and my own traffic folder. I am using XP(Sp2). They show up as being added in Ttools but the planes do not appear in FS9. I never had a problem before I started with a clean install on FS9. My proceedure is this: Decompile traffic source files. Edit source folder,save and exit. Compile source folders. The traffic file appears in Senery,World,Scenery. Ralph

Several things:Did you add the aircraft to the aircraft.txt and are the airports you are adding to the flightplans.txt file in the airports.txt file.You might want to download AITM - http://www.molitor-home.de/FS/AITM or yRoute - http://www.spacejock.com/ to help in determining what may or may not be the problem.W.

W.Seifert Solved problem. Installed fs9 and update on 2nd computer. Used uninstall update and then uninstalled fs9. Started with clean fs9 install and everything seems to be going well. Will try the update later but now I have a scenery file that is NOT corrupted. Thanks for your interest. Ralph(rnails)
