Whats happening, I think, is normal. It sends you to the gamengame website when you click "log on" with every game. For games currently out, after you've logged on on the gamengame website your immedietly redirected back to the page you started off at.
The only reason this isnt happening here is because the game isnt out yet, so theres no reason for them to make it log on capable right now. I dont know how memory works online, but Im sure COMPLETELY unncesary logons are something that doesnt help the server they are trying to get up in time for...tommorow.
So just relax. If your going to understand any of what I said, get this, once the game is actually out I guarantee you that you will be able to log on.
