But if you are on the NA server, it may be server load. Try closing your game and trying again in a few minutes."The European megaserver will be offline for the update to version 1.0.1 starting around 10:30 PM BST. We will let you know when the server is back online and open."

For NA, if you're having this problem you need to press the "Game Options" marker (below the 'News' header) in the launcher, and select "Repair".
