Cryengine makes me cry

I was just about to start taking images and video of my work and the cryengine file corrupted. I then went back to my previous saved version of the environment which also corrupted in the process. I then inserted my usb drive into the computer to replace the corrupted file with a previous saved version that was on my usb to then work off that. However in that process the whole usb corrupted and all my files are now lost ;(.
