Just put ours together, played for a while in the initial missions (set up the buttons mostly), and then noted the WiFi and update buttons after we exited to the main menu. After adding a Wi-Fi password and having it show that we are connected, I clicked "update." Nothing happened -- but now I'm frozen out of everything else. It just keeps showing the screen with the robot, but the only button I'm able to click is "update." I click it, nothing happens, but I can't seem to reboot or exit out. Thoughts?
