The issues on the North American and European PC/Mac megaservers have been resolved at this time. If you continue to experience difficulties at login, please restart your client. Thank you for your patience!
EU login has been spotty for the past couple of weeks.
It's intermittent. Sometimes it's fine, but half the time, it's really slow to log in (compared to NA, which has been fine this whole time) or it'll just time out entirely. You just gotta try again until it works; usually get in within a few minutes.
