Houston, we have a problem

A quick note via my new lap top.. seems my old lap top has Alzheimer's and can't quite find any file I might need so I am in a funk/panic that I have lost most of my work. Lost as in.. it's in there.. but where? I suspect that I am going to have to do my whole set of instructions over again and it makes me want to put my head in my over.. the only bright side being is that the photos are still on my camera and I have a hard copy of my work to refer to.
