Is this to log into the EP server you guys are talking about? well its been down since CR2 went live, so don't expect to get back into it any time soon, unless the devs are going to test more stuff on us.
But if your trying to access the live servers, that is a problem. Click on the "check for patches" button, then let it scan and do it's thing. don't press the restart button because it just screws it up. It should auto restart on its own, and will check for updates. Hopefully it will download the new client and you'll be off the see the Oracle and Agent Pace and what not in no time.
Otherwise, you might just have to call tech support and have them tell you the same thing I told you, or they might say that the update server hasn't been updated yet, and to log in some time later so you can download the patch.
