Can't download

Hey there! So, I decided I wanted to start Warmane again and made a new account. I have a Toshiba laptop with Windows, and went to download Wrath of the Lich King, put in that I use Windows, and clicked Download. But it didn't budge. It didn't even load. It didn't do anything. So I downloaded Bittorrent and tried following the steps, and it still wouldn't budge. I don't know what I'm doing wrong. If you could help me figure this out I'd appreciate it!

try a different browser, it seems chrome has some problem or you can also try the direct downlaod ( so No torrent) http://forum.warmane.com/showthread.php?t=280398

I did this, and it said it was invalid.

what is invalid?

i downloaded it and clicked on it and it said that it couldn't open because it was invalid.

eh, but I also told you that to solve the "download" burrot probem you need to try a different browser, did you try it?
