I was able to play earlier today and I wanted my brother to be able to play along with me so I bought another copy and installed it on a second computer. Two accounts. Each have a key tied to them. Computer 1 can't connect to battle.net with either account. Computer 2 is able to connect with either account. Computer 1 is getting error 3003 saying the server is offline. How is this happening if computer 2 is able to get on and play?
