Collections missing - unable to locate catalog
I have lightroom classic purchased and installed about 6 mo. ago. This morning I logged in and all the collection I set up were gone. I never moved anything ! Now later today everything is gone including the catalog. Luckily I have back ups. I am leary of Light room because in talking to a photographer I know he had the samr problem and lost 30,000 images! I am told to only use lightroom for editing.
Can anyone giv me their thoughts. Is this a common problem and where do I go from here?
How do I get Adobe involved?
