It's not just you, it's not working. I was trying to get this working before I went off to work, but it looks like that's not gonna happen.
I logged in once (about 8:15 A.M. EST) but every time I tried to start it, it told me tilemap null. So I went to restart it, and now it's auth failed every time. Surprisingly it worked without fail for about 10 hours yesterday, which I don't think has happened in weeks.
