Nibble says low battery

I just got my nibble today and started building it, when I finally finished I put the batteries in and turned it on, but it said “Low Battery, Shutting Down” I tried replacing the batteries, but no luck. Any ideas? EDIT: it works now! For some reason it just turned on out of the blue, now the issue is that when I try to press the a button to start a game, the system restarts
