Had trouble logging in the warcraft site O.o anyways..

Game: Warcraft III: Riegn of Chaos.
Op: Mac.
Objective: Finish download so i can play on battle.net
Story: So i launch the game up. I click "Battle.net" (havent played in 2 years)
"Downloading Update 1% 2% 3%".I go downstairs for a couple of hours. I come back its still on 3%...

Any help? If anyone could find the download link on the site i would appreciate it.
