My copy of SkySafari Pro 6 Mac (App Store version) is suddenly unable to update "Update Minor Body Orbit Data." It was working fine prior, and my Mac is connected to the internet and the web browser/mail continues to work fine, so my basic connectivity seems to be OK. I'm running Mac OS X v 10.11.6. I also note that "Import From Online Depository" returns a blank frame; previously it had worked fine also. I suspect that a settings file for SkySafari Pro has been corrupted somewhere, but I have been unable to find it. Any thoughts?
Thanks in advance,
