Bypass Server Status
Type this code at the pre-login screen (first screen) after pressing the [Play] button:
[Up], [Down], [Left], [Right], [Up], [Up], [Down], [Down]
It will let you play the game even when the server is down/is set to Busy. This code is can also be found on the official website of the game in the support section. Bear in mind that the server is Busy for a reason.
