FSX:How can I reset all my fsx certificates, logbook entries, pictures, medals, etc?

reload FSX, put in the disks and hit repair, then hit do not save game files, if that does not work uninstal it and it will ask you again along the lines of delete saved game files, click yes. if you go to start/my doents/flight sim x files you can delete flight plans and saved videos and stuff, but i have messed up my logbook doing that, i deleted the file or something then i had to reload fsx so that the files would save there again. and try searching for the files in the program files flight sim x folders, alot of the games files and data is there.
