Isn't that the quest that causes the game to lock up and have to force the game to close just to play? If so bro, just skip it. Not worth all the headache to try and get it to work.
Just go to kunlun. On the way to forest of tigers. Kill some foxes there and get bead of fox and you'll be able to finish the quest. Some quest appears in KL when you get a particular stuff from certain mobs/bosses. You'll notice another rtf will popup when you get horn of blue dragon and shell of black tortoise. You must had bead of fox before but npced or deleted it.
