Lightroom catalog suddenly disappeared
So the other night before bed I went to shut down my computer, closed Lightroom and it prompted me to backup, so I did (I always backup when prompted weekly). Next day I fire up the PC, open Lightroom and it's completely empty and starts the tutorial (where the arrows point important sections) as if I had first opened it. The library was completely empty and the catalogue disappeared. I looked in my Lightroom folder (Pictures>Lightroom) opened the catalogue inside and it's empty. I contacted support, they took remote control of my PC and tried to open a backup catalogue, but the most recent backup is from January, and after searching my whole system for a .lrcat file the support advisor just told me that it has gone for good and they couldn't help any further. All the collections photos are still synced to lightroom mobile and web, so I can access them on there, but the desktop catalogue is gone and when opening my old one it will resync with mobile and ill loose all the edits.
I have tried everything I can think of, but how can a catalogue just disappear with 8 months worth of backups?
I'm currently running a disk recovery programme to see if I can recover anything that's been deleted (not by me)
Has anyone else had this issue, and know of anything I can do to recover my catalogue?
I'm using the latest version of Windows 10 and my Lightroom CC is updated to the most current 2015 version.
Thanks
