I checked, but I was able to login perfectly @levidisonglo... can you refresh and try again? Maybe there was a server timeout that occurred during your attempt to login?
If this doesn't work, try using FireFox to login to your game. I used this browser and it worked fine.
@levidisonglo That particular problem is usually caused by your computer's date being wrong, and years in the past. Try changing it to the present time, and synchronizing your internet browser's time as well.
