When I press any button on the M1 Slingbox (Mac version desktop) TiVo controller, nothing happens. It has worked for the past 4 months and no longer works. I have not discovered how to re-configure it. I deleted the desktop application, emptied the trash, downloaded from Slingbox and installed it. Still no luck and no configuration appeared as stated in Sling support. The streaming L.E.D. is on in the L.E.D logo light. When I push a button, the next light in sequence lights, the screen blinks then nothing. The additional light goes out.
