Database empty

[Fred]

Hello,

My log contains the following lines

Sep 1 13:53:03 LogicMachine user.info sysinit: md5sum: WARNING: 1 of 1 computed checksums did NOT match
Sep 1 13:53:03 LogicMachine user.info sysinit: /lib/genohm-scada/storage/db/backup.db: FAILED
Sep 1 13:53:03 LogicMachine user.info sysinit: md5sum: WARNING: 1 of 1 computed checksums did NOT match
Sep 1 13:53:03 LogicMachine user.info sysinit: /lib/genohm-scada/storage/db/current.db: FAILED

And it seems I know have a completely empty database. Of course there is no recent backup...

Anyway I can recover anything out of it, even manually ?
I am not even sure how to access /lib/genohm-scada...

Many thanks
