I contacted chat today. They asked what kind of batteries I used. I said new energizer alkalines. Then they asked if that light near the battery compartment was blinking. I said nope.
So they are sending me a new battery pack.
I don't think it's the battery pack, although I hope it is(easiest to fix), I think it's the connection that the battery pack cable plugs in to. If you ever get a chance, look in that hole that the battery pack cable plugs in to on the Atlas. To me it looks to deep to make a good connection.
