Hi Elizabeth, It sounds like either the photos didn't completely delete off the memory card or the card's memory is being filled up by unwanted cache. You can try to plug in the card to your computer, right click on the card icons, go into the settings of the card and clear the cache. If that doesn't work, or the cache is unable to be emptied, you will most likely have to get a new memory card. I hope this helped, good luck. Jeff
