Encrypt Password

Hi to everyone.

I created already a database with table EMPLOYEE_RECORD and has fields of username and password that has already records (MS ACCESS).

MY PROBLEM:

When I checked the Encrypt Password in the USER LOGIN and GENERATE IT, THE USERNAME WITH THE HARD CODED PASSWORD THAT ALREADY EXISTED in the Database CAN NO LONGER be accessed (Invalid Username/Password)

BUT

When I UNCHECKED THE ENCRYPT PASSWORD, AND GENERATE IT AGAIN IT ALREADY WORKS!

But that is not I WANTED.
