Seems like your logbook.bin got corrupted, and when that happens FSX wont start. Other than doing a reinstall, move your logbook.bin to a different folder, fire up the sim, it will write a new one. If that works you can try putting back your orginial logbook.bin and try to start the sim again.
I hate to tell you, that most likely, you will have to start with a new logbook.bin, which means you'll lose all your hours. It's one of the most annoying glitches with FSX, so i always back up my logbook.bin after every flight so when it gets corrupt (which it eventualy will) I'll be able to load my last log and only lose that one flight.
