I've fought and killed the cultists and taken the note. When I get to the dock and board the ship I cannot get a dialogue to start wtih the captain. I've deleted the add-ons, reinstalled, emptied caches, deleted xbox live profile and redownloaded. Went to earlier saves but nothing works to get the dialogue started. He just keeps saying "need something, can I help you?" I'm playing on an xbox360 and am at level 20. Completed the Horn and Voice quests with the greybeards.
