Technical issue, game will not start

Hello.

I just downloaded the cataclysm client with utorrent from warmane's mirror. When I try to run the game, I get this error;

"Cannot stream required archive data. Please check the network connection."

I tried these steps to overcome the problem in my own way;

-Tried launching with both "read only" ticked and un-ticked.
-Turned my firewall off. (tried it with on aswell)

The error message carries absolutely no meaning to me as I'm obviously connected to the internet... I would appreciate some help. Thank you in advance.

Bump, please send rescue

Any advice on this? I'd love to play cata

Found this on one of Blizzards forums:
'Hold down the Windows key on your keyboard and press the 'R' key. This should bring up the Run dialog box. In that box I want you to type inetcpl.cpl and hit OK.
Once the Internet Properties window comes up, click on the 'Connections' tab, then click on 'LAN Settings'. If there is a check in the box next to "Use a proxy server for your LAN," or "Use automatic configuration script" uncheck it'

But also you should now that Cataclysm is getting decomishioned so i don't recomend starting a charecter there, read here.
