Hello, That's my first post and I'm from Brazil, so sorry for any mistakes.
Well, I came back to this game and I was planing to make a mission using MechJeb, my game version is 1.8.1 and it doesn't start when I put the MechJeb in the Game data folder, it just keep loading the screen for ever, and I'm sure it won't run because I went out for 2 hours and it was the same when I came back. So, can somebody help me?
