I've been plagued by the error:

"An Unexpected Error has occurred. Exiting FINAL FANTASY XIV.(17)"

At first it would freeze my game after a couple minutes of logging in but now it's appearing while I try to login into my character and kicking me out of the game.

It's happened before to a past character (only lvl 3 so I didnt mind) which I deleted but now it's happening again to my new character. I'd rather not have to keep making new characters only to be unable to play them 10 levels in.

Any suggestions on what's causing this?
