Getting Account server connection time-outs when trying to log on here. Already patched about an hour ago, and now launched the game directly as the launcher itself wouldn't load. Seems there's still part of the servers that isn't online yet.
edit: as with others before me, it seems it's more a hit-and-miss kind of thing. I tried the launcher again, after taking almost a minute to load the launcher, it finally showed the engage button, after which things worked fine.
