help im an idiot

[Bob]

er... assuming that it was downloaded from inside the game, after it completed it should have coem up with a box "click here to restart DiabloII" or similar, autopatched, and restarted the game... have you tried connecting to battle.net since? or did you download form the website.

in short:
you shouldn't have to do anything, it's autmatic except for a few boxes where you only have 1 button to click anyway.
