Game crashes on character loading screen

I am playing a monk and killed the executioner in Ogham. I attempted to enter the Ramparts and the game crashed out to the desktop. Now every-time I attempt to load this character the game crashes. The character has become unplayable.
I restarted the computer and updated graphics driver, but no difference.
Does not happen to any other of my other characters. Character is in DotH league, Australian Server.
Thankyou
