Telescope is ACP->Driver for telescope connected through TheSky
There was a problem initializing the support library:
The telescope is not connected.

so this happened during the course of the evening? What do you mean "shutdown"? Whatever ACP observing plan is about to be run, this is a startup problem for that Plan. It has no idea (yet) that the Plan contains a #shutdown request. (I am guessing here, based on the "shutdown" that you mention). ACP is functional at this point, but it discovers that TheSky has disconnected the Paramount and so cannot proceed.

> no shutdown at request

I am not sure I understand... sorry Adam :-(
