So I downloaded 1.5 and it'll play, but when I install making history, it will tell me that I need to download either 1.4 or higher to use yet I'm using 1.5. Now if I download ksp using the zip folder, it will install yet I'm hit with another dilemma. When I try to play the game period, modded or not, it will give me a message saying "mono." I use the website, not steam so I'm really all out of ideas on how I should approach this.
