There have been a few people with this problem lately. I believe the problem was fixed by just letting the game run idle while they did something else. One person said after about 20 minutes, it finally moved into the game.

According to QA, there's a problem with the Balance Files being downloaded when you first start the game:

Hey Shadow,

I've looked into your files and I can't see anything much wrong. My first instinct would be to say that it's having trouble downloading the Balance Files for some reason, as this seems to be the part of the loading sequence it's stopping on.

I saw Wolf, in another post that was created about the same issue, mention that it inexplicably took 20 minutes to load. Have you tried just leaving it for half an hour and see what happens?

Cheers,

I know that the devs are looking into the issue, so hopefully they will have a fix soon.
