I have been watching Sky Go on my work pc (long nights in the office alone) with no trouble. It was the third device I had registered. A couple of days ago I registered the last device, which was a new pc at home. Sky have removed my work pc, added the new home pc and left the 4th device slot free. Now I can't re-register my work pc as I've already made one change this month!!!
Why wasn't the new pc registered in the empty slot??
