Hi,
I just picked KSP up from the store - I've been running the demo for a year now and finally got around to buying the full version - yay! I played around for about 2 hours, testing out the...everything, but then I deleted my tester save and started a career mode game. Unfortunately, it never loaded. The application became unresponsive and I had to force quit it. I have since tried making new saves, starting scenarios, starting lessons. It seems that whenever I start any save of any type, the game kills itself.
I have no trouble with loading - it goes smoothly and I'm able to use the title screen just fine. I've tried uninstalling the game and re-installing the game, nothing changes.
I bought the game off of the KSP store - I am not using steam, that's right, I'm not using steam. I don't run any mods, heavy programs, or other games and my computer has ample RAM, so it's not that. It's a game internal thing, because it was working before.
I run a mid-2014 Macbook Pro running Mac OS X 10.11 with 16 GB of RAM.
Hopefully I can leave the spinny-beachball-of-death behind and actually play KSP!
Cheers,
