I think that happened to me too a little while back. Except like this: After he hit his head a lot of times because his rover tipped over a lot, he remained like that and I'm unable to do anything.
Hi! Welcome aboard! I hope you will enjoy your stay! When I was first playing KSP, I used MJ too. I learned how to establish an orbit, land, dock, rendezvous, etc by watching MJ do it. I still use it though. Happy launching!
And I think KMP is updated, just used it a little while back to play LAN with my little brother. But I haven't got the game yet, going to buy it next Tuesday.
