Follow standard procedures to recover from a previous copy. If you run automated backups (the kind set in the Web Crossing GUI...not a system backup) and have not performed a manual backup since receiving this message, then your backup (webxdb.1) is not corrupted and you may recover via normal methods: Corrupt Database, What to Do.
However if you have performed manual backups while this condition exits, then you have moved the corrupted database into your backup.
