Yeah, was reading some stuff on their forums and twitter just now to see how things were going and saw that they indeed got this fixed. Hopefully nothing else weird raises its ugly head for logging in. I know there seemed to be no issues in the game except for my system having a tad bit of lag at first whenever zoning into Gridania where lots of people were.
Hopefully, today they get the preorder code site working. Despite the issues that came up they are working to fix them as best they can. I'm sure the preorder site issue couldn't have even been tested for to see if it would explode with our onslaught yesterday. =) Some things you just can't overload enough in testing until thrown to the user.
