Cheryl, my guess is that it became so root-bound, that simply watering it did no good. The water just ran straight through and out the drainage holes. If you are going to keep it intact as in the photo, I would place the pot in a large basin of water, deep enough that it comes to the top of the soil, and let it soak for several hours. Do this weekly until you know whether the plants will survive or not. Mist the leaves 2-3 times each day but have good air circulation so that the leaves have a chance to dry out between misting.
If this were my plant, I would divide it, separating the pups from the "mothers". Pot the pups up separately. Keep all the potting soils slightly moist, never allowing any of the pots' soils to dry out. If you lose the mature plants, perhaps you can save the pups. Perhaps you have already done this.
