Have you tried this camera memory card on your computer?
If this memory card can be read functionally on your computer, you'd better copy off all your stored photos to another memory card or drive and format this card immediately to check whether it can still be read on your camera.
But, if this card unfortunately also gets some problems, you'd better try to apply a memory card photo recovery freeware to get all your stored photos back successfully for free:

It is possible to recover formatted memory card only when you don't save any data to the formatted memory card. Because when you format memory card, the data remains there but the space it occupies is made available. So after the first format, you'll be able to carry out formatted memory card recovery with a near 100% success. But once new data is written to memory card, the chance of full memory card recovery will become less.
