Can't log in. "Unexpected Error has occurred (17)"

I went to teleport to Limsa and my game crashed giving me the "Unexpected Error has occurred. (17)" message and ever since I can't log into that character. Does anyone have any idea what I could possibly do? I would just contact support, but they aren't working today...

Edit: I can access other characters on the same account, I can access characters on my gfs account, and she can access my character, but I still can't log into my character on my account.

Edit 2: Now I can access my character somehow so this thread can be closed.
