Sounds like the recovery software wasn't able to do its job. Do you have any backup catalogs that you can revert to?
Since the size of the catalog is 0 bytes, it means that the Catalog does not have any information in it.
So I would suggest you to please try to work with another Catalog from your Backup.
Sorry I dont have any backup from my catalog.
And yes I already used 2 recovery software programs, Recuva and Mini Tool Power Data recovery. Both doing the same think after 8 hours of deep scan. shows the file with correcto name but no info (0 bytes)
