Just an update for everyone who reads this looking for help - my problem turned out to be the university internet I was on. Still can't speak to why the .zip and .rar files I downloaded through my browser didn't work. But I'm at my friends place now downloaded the torrent with torrex from the windows store and I'm getting about 5mb/s. So to anyone having the same troubles I described above, I'd recommend going elsewhere to download if you can. And thank you for your help Zelta. Looking forward to getting on ! :)))
