Hi all,MY aircraft in FS2002 start bouncing and jumping all around each time i start the sim.so i reinstalled fs2002 but it 's still the same.anyone an idea?thanks.olivier

Did you change any drivers for your graphics adapter? Did you update any other OS software? Have you installed any third party aircraft, scenery, etc? Did you reinstall fs2002 overtop the existing fs2002. If not, did you uninstall fs2002, open Windows Explorer and delete any residual fs2002 folders? If not, try this:Rename your fs2002.cfg file to fs2002.cfg.OLD. Restart fs2002, let it stabilize, then check to see if you still have the problem. If you do proceed to the next paragraph.Copy your fs2002 folder and rename the copy fs2002OLD. Uninstall fs2002 using the Windows Add/Remove Programs menu. Once uninstalled, open Windows Explorer and delete the residual fs2002 (NOT the fs2002OLD folder) folder. Reinstall fs2002. Once installed, start fs2002 to see if it is operating correctly. If so, rename the new fs2002 folder to fs2002NEW. Rename fs2002OLD to fs2002. Restart fs2002 and see if you have the problem again. If so, rename fs2002 to fs2002OLD. Rename fs2002NEW to fs2002, start fs2002 and check that the problem disappeared. If the problem disappeared, then you have several choices:1. Add new items to the new fs2002 from downloaded files.2. Slowly copy files from the fs2002OLD folder until the problem recurs. When the problem recurs, then remove that input.
