There also seems to be a hacking problem. My account (even though I havent used it since GW1 start) has the email changed. I got all the confirmation emails, but never clicked them actually. So now my email is changed and I cant access that account anymore. No problem, since it just bogus data in it and no game associated with it, but I did a quick search about this and there seem to be a lot of others with the same problem, with an active GW2 account.
No official statement yet, those people havent even got a reply back from support.
Waiting for BIS to come back to their senses and do a real ArmA 2 successor.
