Fruit Machine Chat

Hi recently purchased a poker face fruit machine with I believe the mayday epoch board had several problems I've managed to fix them all except every time the machine is powered up or doors opened it says validating game this takes aprox 5 min then boots as normal is there a problem causing this or is this normal any help very much appreciated

Once its powered up and validated then doors have been closed, dose it happen again once the doors have been opened and closed again
