Freezing and projects disappearing

I've been experiencing a lot of freezing and issues with refreshing my Adobe Platform. It takes a very long time to refresh and it freezes all the time and stuff doesn't appear as It should. I'm also missing a page in one of my Projects file I need to determine how to retrieve it or what happened. It just disappeared. This is not the first time the first time I thought perhaps I might have accidentally deleted one of my animation projects, but I'm certain that that project disappeared as well as this one it just disappeared. One day it was there and the next day without even interacting with the project. It was not no longer there.
