My family and I just got back from Disney. Both of my kids are big Star Wars fans and they each built a droid at the Droid Depot. Trouble is we got home and one of the droids is not working. I did a factory reset, but I can’t get it to link to the remote. I press the button to connect it to the remote and the light on the bottom of the unit does not flash or come on. When I switch the unit on and off the light flashes quickly several times and that’s it. Any ideas? I have one happy kid and one devastated kid. Thanks so much!!
