"No response received"
Although I have managed to resolve the problem for the time being, does anyone know why, sometimes, when you log into your adwords account, on the left side of the screen, where it normally shows you the name of your campaign and adgroup names, it sometimes displays "No response received"?
I take it this is some form of communication problem with one of Googles servers or something?
I think it's happened to me twice so far. It can be very annoying when it happens.
