(FYI, I was only able to view the links in Acrobat, not in Preview.(Wanted to make sure that everything worked *first* before I did that).I was able to connect our SBIG STL-1001E camera and take pictures, no problem.(Actually, it gives that same error even if I don't plug in the telescope USB cable at all.) Similarly, I cannot connect to the focuser (Optec TCF-S).
It gives the same error as when trying to connect to the telescope.
I just bought it 10 days ago and I downloaded a fresh copy of Sky X Pro just this morning using this link: that is 3 years old, then you guys might want to update the link.
