Just for fun I searched Google for "Sync matching failed." I found an old post on the Sequence Generator Pro forum that talks about time zone on the scope versus the computer. The scope is a 10 Micron, the error was 15 degrees = 1 hour, and it was exactly that error message. The discussion was disjointed, but the last post said that the person fixed the time somehow. I wonder if 10 Micron has a limit to how far "off" the mount can be? Check the time and time zone on the mount and the PC.
