My Olympus battery charger isn't working!!? - olympus charger flashing

I have an Olympus LI-42B digital camera, but I have an L-40B Battery Charger Olympus, operating on the battery until today. It uses light to turn red while charging, then blinks green once completed. It is so far the light and the battery is not charged. What should I do? Please help, I urgently need the cameras !!!!!
