I go to download it and when i click on download it takes me to "are you looking for unity webplayer?" No, I'm not. I downloaded it 3 times now

It's on that page... Big blue button... The first thing you see when you open the page is the webplayer, so you need it to load the whole page... Try a new browser if that doesn't work.
