I'm getting the same problem.
My character's image and their info aren't showing up on the character select screen. I can still click their name as though I were going to log in normally. After selecting my character, the loading screen picture is the world map, which I've never had before as a loading screen picture. A few moments into the loading screen and an error message with "World data could not be obtained. Please try logging in later." pops up. There's a yellow "3070" on the bottom right of the error window - not sure what that is. Pressing "ok" returns me to the main menu.
