Can't start the game!

So,i downloaded the game via torrent (pandaria 5.4.8) and when i try to run it,i get the following message:
''Failed to download the data. Verify your internet connection. for more information, visit https://battle.net/support/article/6961''
(im in Brazil so obviously the message comes in portuguese, but thats kinda the translation)

someone help me plz

Did you download from Warmane's site or somewhere else?

Warmane,already tried restarting the pc,dismarking the ''read only'' option in properties,but nothing worked.

Check realmlist and make sure that you use your username to log into game, not @mail
