Hi Kurt,
Please see this thread
http://forum.mainsequencesoftware.com/t/how-to-ask-for-help/26 and we'll
be able to help you better. What versions of SGP and PHD2 are you using?
My guess is that you have not configured your PHD mount settle time
properly. SGP might be waiting for PHD to finish settling and because the
parameters are too restrictive PHD never fully settles and SGP times out.
If you go to Control Panel/Auto Guide tab, what are the "Settling Options"?
But again a log file as described in the linked thread above will be most
helpful.
