From GPSur Dr. Erhard Regener:
Databases may be damaged rapidly by a crash, even if the hard disk contains no errors. The corresponding program may show inexplicable behavior, false calculations, or absurd results. Often user make mistakes to reinstall the whole program. But the reason is a corrupted database and not the program itself. Dr. Regener Paradox-Table-Repair verifies table errors and repairs the database in most cases. So it avoids loss of data, data backup, or reinstalling of the whole program. Dr. Regener Paradox-Table-Repair provides you with detailed information which tables are damaged.
