If you have? I'm not too sure, on a vet character you can just change the dungeon mode and change it back, which will reset the arena/dungeon. I'm assuming there's a timer by default on resetting the arena once it's finished, they talked about it in an ESO Live episode ( can't check at the moment, but will do when I'm home if it still hasn't reset), perhaps a few hours or a day?
