The servers aren't even open, that's why. Right now they're doing tests, so they'll limit who plays and when they play. As of right now, I only know of 2 dates, 11th and 15th so wait until than before asking anything about logging in.
I'd also like to point out, during the last test (people were limited, I was accepted though), the first few days, some people had trouble logging in. (Including me, it was in the news but it was fixed for me on the last day)
