I started a career mode game and got through the basic contracts such as getting out of the atmosphere. It then did not show the orbit kerbin contract. I Googled it and all i saw was that it happens when your reputation is low, but i never failed any missions and i did all of them perfectly, i also tried doing some side contracts but it did not do anything. I started a new game and it gave me the orbit contract, but then it did not give me the mun contracts, so again i tried doing some more contracts and it did nothing.
