If you try to run from the command line do any errors get written to the console?
So far I did only a bit of expanding/updating of the original XML planetary records file. I was thinking of making a similar file for stellar bodies, but the stars didn't align so far for me having both time, motivation and my brain not being utter goo at the end of the day.
No pressure there.This is something I can probably automate in the new version. Still going to be a way off, I'll keep it in mind.
