I recently got KSP and have been having fun in sandbox mode, and I decided to start career mode. I went to start a new game, and career mode was greyed out so I couldn't play it. I figured that it was because I hadn't completed the tutorials, so I went and did those (although I can't complete the orbiting 101, it says to get the orbit path to nearly circular, and I got the eccentricity down to 0.002, and I still couldn't move on. any help here?). I have no idea why I can't do this, as I could easily start career mode in the demo version. Please help, I don't want my money to have been wasted!
