Ah I see what you're doing wrong, you need to click download and then save don't click open. Once saved, it'll download a .rar folder, use winrar to open the folder. It might not detect the folder as a .rar if you don't have winrar installed, and it'll probably identify it as an internet icon or some shit like that. Just download winrar, then use winrar to extract the .rar folder, once extracted you can open the folder like normal and play.
