If you've already tried closing and restartin FSX, and that didn't work, and have already totally shut down your computer (not a simple restart), and it still does'nt work, try deleting your FSX .cfg.
I had that same problem a week or two ago, and something along those lines fixed it. I think it was the .cfg thing, but it may have been shutting down the computer, and restarting.
