i just bought th starcraft battle chest, so i tried to get on battle.net. (why get the game if you won't ever play online), but when i try to access battle.net, the game says that i need to download an update. i say ok. after it says that the download was succesful, but the system needs to restart the application. i once again click ok, since there's no other option. however, instead of restarting, the game takes me back to the multiplayer optios and sas that the update failed. does anyone know what i should do?
