The Dink Network

I am playing the version I just downloaded from the site, it is 2.0. I accepted the quest to kill the slayer that was stealing food from the village, before going to the cave near the well I talked about it with the farmer woman and I also found the good wizard's house nearby and also talked to him. He said that I must kill the slayer first, so I went to the cave, killed the slayer, had a small talk with the evil wizard, returned to the village, talked to the farmer woman that said that I need to talk to the wizard but when I went to his house all he says is "Please help us Dink".
