Username and Password Implemented

Worked like a charm the very first time. My donation number is 12 digits after unplugging the box and plugging the power back I added that 12 digit number into both the username and password box then pressed the OK button and it loaded up with out issues, not sure if this needs to be done each time box is rebooted.
 
I have two mag 254 boxes onemy other with the donation i knoew and it worked right when i put in donation. i lost the donation for the other box so bought new one. i linked mac to donation but still gives error. not sure why they had me change the server and portal but still just error. how do you wipe it clean and start over and where are the factory files? Code checker is down now too
