In case you still dont know, its on blizzards end, not your pcs fault. I bought the digital and gave up on it after countless attempts and errors. I just borrowed my friends cd and installing it from there. Kind of pathetic that I have to do that when I paid for something that should of been working properly. I suggest that if you guys have a buddy that has the game, borrow their disc and install it from there. Pathetic, but seems to be the only solution since Blizzard doesnt give a dam.
