I just signed up for slacker premium and attempted to log in via the model s. It has become stuck trying to load or something so that it just constantly shows the "working" circle and the login in the background is grayed out and cannot be changed. Any idea what I should do? It's been like that all afternoon. I've tried turning the car off but that did nothing. I guess I could reset the touchscreen. How do I do that again? Anyone have similar issue?
