I choose the expansion and the operating system then click on download, then the whole thing resets, no download window or anything. The Expansions listed are as follow: Wrath of the Lich King (old), Mists of Pandaria, Cataclysm, then Wrath of the Lich King. But I've tried all of them, they all reset when I click on download.
I know my anti-virus or firewall is blocking anything. I just download and ran Warframe this last week.
Had BitTorrent on my system but it seems it couldn't find it, so I got rid of it and installed uTorrent, now it's finally downloading. Can't figure out why it couldn't find the other Torrent program? Maybe because it was an older program?
