Yeah I have been having this exact same problem. I enter my username and password correctly and I click log in. At first, it says "Connecting to Server....." and then the whole window goes unresponsive, and then it just says "Can not connect to the server" I have tried logging in many times this week and nothing is changing, so it can't be the queue. My computer is also very smooth and I haven't encountered problems with any other program. I'm starting to get a bit frustrated because this game seems fun and I was hoping to be able to play it at least once, but nothing. I have tried deleting it and reinstalling too, but that doesn't help either. Oh well :Sleeping:
