I am unable to carry on with the gladiator quest - Ul'dah's Most Wanted. I have done the quest up to "wait in ambush for the freelancer" and when I click on the destination, I receive the following error message "A system error occurred during event movement".

Even after abandoning and selecting the quest again, the same error message occurs. Please help.
