1. Did you open the database manually?
The database file of ezPaycheck payroll software is .mdb (Microsoft Accesss Database) file. This file is NOT designed to read manually. You need to read it with ezPaycheck payroll software.

Please feel free to contact us if you still have any questions.

Thank you.
