Schlage Express: Why does generate program files continue to blink after HHD is returned to PC?

This is a known error but does not have any effect on programming doors.
It can sometimes be corrected by reprogramming the same set of doors and with Express running allow the hhd and pc the sync again.
As last resort back up database /uninstall software /reinstall software/restore database backup. 


The message can also be turned off.
