FS9 Shortcut keys not working

Hello guys,I had reinstalled Flight simulator 2004 and applied the patch 9.1.I had aso installed the PMDG 747(including the update).I know it has nothing to do with the Addons i installed.But when i start flight simulator the keyboard shortcut keys are not working.All the shortcuts of Flight simulator seem to have vanished.All the assignments have also vanished.I had to reassign the keys.I need help.Is there some file i can replace or something to assign the shortcut keys back 'coz it takes a long time to assign all the keys.Thanks in advance,-NavneetFS 2004 Version 9.1AMD Athlon 64 3000+ATI Radeon 9600 128MB - Anti-Aliasing 6x1GB DDR400 Kingston RAMWestern Digital 30 GB - Seagate 120 GB (7200 rpm)Sony DVDRW - 16XLG Flatron 775FT 17' MonitorCreative SBLive!
