KSP v0.90.0, OSX v10.10.4 This is the first time I have ever used KSP. I downloaded the demo but when I open it it acts normally until I try to click Training or Start New. All the other buttons in the main menu work. I have tried to delete the settings to reset it to the default settings, but it still behaves the same way. I need this game for a school project. Please help!
