how to download?

i'm gonna sound dumb as hell now, but i can't figure out how to download the WotLK client. i filled everything in, that got asked of me (aka, which expansion and windows system), but for some reason i can't download the client.

anyone else had this problem?

it is done via torrent, so you need a torrent client.
I recommend https://www.qbittorrent.org/download.php

In case you already have torrent client but still nothing happen, try with a different browser
