unable to connect to authentication server

when I click login, after around 45 seconds of trying I get: unable to connect to authentication server This error happen no matter what I use for username or password.

been happening all day for me, so no open beta I guess.

I have played lots of other MMO games, D3 etc are currently working..

I don't run a firewall so it is not being blocked.

Win 7 64bit, everything else internet related I can find is still working perfect

Installed on D:, re installed on C: this afternoon with all default settings same thing....

Any help anyone?
