Can't get unreal ed 4 to work

i would like to make a ctf map for ut4… In projects I go to browse(http://i.imgur.com/AcYgrLn.jpg?1), then UnrealTournament-clean-master(1) which i downloaded from github.com/EpicGames/UnrealTournament, then i open unrealtournament inside the folder(http://i.imgur.com/RBNrWD2.jpg?1), then it says “this project was made with a different version of the unreal engine. converting to this version will rebuild your code projects”(http://i.imgur.com/eGMGUIO.jpg?1). converting fails. When i click skip conversion, a box pops up which says “the following modules are missing or built with a different engine version”(http://i.imgur.com/b7PpUQB.jpg?1). I click yes to rebuild them and it fails.
