I can't download Unreal 4 Engine games?

When I try to download a game made on the engine, it doesn’t download. It’s not my computer, because I can download other games, but I can’t download U4E games! I’m downloading one from GameJolt.com. I can’t play it, nor does it download!

Man, i think it is not the place for it. Check with the ppl from the website why it is not downloading, the engine has nothing to do with it…
