As part of my very own Historical Space Race challenge, I recreated the Apollo VIII mission.
And if you don't feel like working your way through the mission report, I've got a bit of video here with the Kerbin-Rise as required.
The only way is to uninstall the mod. Personally, I recommend having multiple installs of KSP. Myself, I've got a no-mod install, a light mod install, and one that I really need to clean up with all the parts packs.
The only other suggestion I can give is to start with a fresh install with no mods and see if that loads. If it does, 8nstsll and test 1 mod at a time until you either get them all installed OR the game crashes on load.
You want a big...what? Sorry, I'm deaf in one ear, so you'll have to repeat your order, and you'll need to accentuate and speak slowly.
Waiter, I'd like a refill on this iced tea!
Granted. You CAN have a stronger computer, but you don't.
I wish I was fluent in every known human language, both current and ancient, including all languages that have historically died out.
