Photos disappeared

The app does a fine job with photo-taking. However all of my stored photos disappeared. They were all there and then they turned black and vanished. They were NOT deleted, so they havent been able to be recovered from scans etc. they literally just vanished. Pics of my brand new baby and so many firsts. Im heartbroken, and cannot recommend this app!!!
