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

Is this the only character that this happens with? Can you log into any of your other characters? If so, you might want to try deleting the locally saved data (located: My Documents > My Games > Final Fantasy XIV). Make a backup of this folder just in case this doesn't resolve the issue.

If after this you still cannot log in, please respond back with a Final Fantasy XIV system report. Simply go to the 'Config' option on the Final Fantasy XIV launcher and to the right of 'System Information' click on 'Display.'

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