Heres what Error 2002 is.

"Final Fantasy 14 Error 2002 - Server Congestion
This error is very similar to error 1017, except to say that FF14 has had restrictions put in place for players to try and prevent servers from becoming overcrowded and creating issues for those still playing the game.

This error will likely happen on the main menu (where it plays the famous Final Fantasy tune) and the 'Start' button will be greyed out.

You won't be able to click start and, if it doesn't become available within a couple of seconds, will mean you're unable to connect to the character selection screen.

This is in a bid to prevent too many connecting to the game and, sadly, cannot be fixed through traditional means."
