Live View on Spotlight Cam times out [ACTIVATING DEVICE...]

I have four Spotlight Cameras and one of them was acting up today. Live View worked a couple of times earlier in the day. But shortly after, Live View stopped working and would never connect. It would get stuck at the "ACTIVATING DEVICE..." screen and time out. The other three Spotlight Cameras have no issues turning on the Live View.My connection speed, etc is all up to speed. And it's worked fine in the past up till earlier this afternoon. Any advice?!
