I ended up calling Demeter and sent it to them for repair, I don't think these are really set up much for shipping as the connections are fragile. Demeter might improve the robustness of the connection, I don't think he charged me for the fix, but it was under warranty as I bought it new. I would open it up, you will probably see where it got loose. I am not great with a solder gun, so I sent it to Demeter. The turn around was pretty quick. Good luck.
