A useless (toy) computer message with no remedial action suggested.
The general meaning is that this is the end of the line and you made the wrong choice in the beginning. Also, a message with remedial action suggested that could have been automated.
I just got a drop dead message that says "UNABLE TO OPEN FILE" as in wouldn't it be nice if the genius programmer would tell us more specifically what the problem is and what we might do about it. If the message says "You must dial a 1 before this number", one wonders why the system couldn't just make life a bit easier.
