Pandaria Can't play MoP

[Schimo]

Hello guys.
So I buyed a new PC with windows 8 and when i download mop minimal launcher everything is ok.
But when i start,it says:
Cannot stream required archive data. Please check the network connection.

My connection is good and i don't know what could be the problem.

Did your old PC work? If so, the problem might be your firewall / antivirus blocking the connection, create an exception.
Alternatively you can download the full client and then patch it with WoD customizations, but you might encounter other firewall issues as well logging in into our realms.
