If like me you have completed all of the missions in Fsx accel and other missions that you have downloaded and received rewards for and do not want to start from scratch should anything go wrong with your computer back up these files and you can just drop them back onto your pc or another pc with FSX on it if you want the same rewards and logbook on a different computer.
1. Make sure the show hidden files is checked.
2.Back up Logbook.BIN file found in My Documents/Flight Simulator X Files folder.
3.Back up GrantedRewards.BIN & GrantedRewardsOLD.BIN found in the AppData/Roaming/Microsoft/FSX folder.
4.Copy the Rewards folder in the main FSX folder if you have added extra missions with rewards otherwise they will not show up.
