Okay, you say you reinstalled and it is STILL there? That should not happen unless you failed to UNinstall beforehand. If this is the case, back up any aircraft, gauges, effects etc that you have added, but do not back up the scenery you have added. Then unintall and return to default settings.
This should fix your problem. If it doesn't, then something is wrong with your FS discs and you are SOL.
