Thank you for the reply Xestor.

If you had no issues on your friend's PC, than it may be something specific to your own PC. When you reinstalled the game, did you delete the locally saved content? This data should be located here (My Documents > My Games > Final Fantasy XIV). This isn't deleted if you reinstall the game so if there is a corrupted file, a reinstall won't get rid of it.

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