Just another Tuesday.
At least now I have an alternative for when the servers are down.
Commander Benggal reporting for duty!
At least you can log on. All I get is 'You cannot login to this server at this time'. >:(
If that persists you should probably check it out on their forums. I logged in just now to see if it was happening to me too and got through without issues. You should definitely make sure it's not some problem with it thinking you're still on the Pre-order key and not the Retail key.
