Latest questions about "fingerprint attendance system v2008"

We have a few employees who used to clock in and out with no problem. Now they are getting error messages that say 'Disabled User'. I can't find any discrepancies in their information.

We are using FingerPrint Attendance System V2008 in the office. Every time I check the logins of the employees, only few are showing. Most of the log-ins are not displayed in the system.
