Good afternoon and thank you for posting on the Final Fantasy XIV Technical Support Forums.

When the game crashed, what exactly happened? Did you get some sort of error message? Were you booted to the desktop?

Do you have any other disconnection issues with any of the characters you are able to log into? Or is it just when you log into your main?

Do you get an immediate 90002 error when you try to select that character, do does it try to load it first?

We hope we can be of assistance in helping you enjoy the exciting world of Final Fantasy XIV!
