[Skyrim-(Dawnguard) ''A New Order'' quest won't start.]

Hi,I have problem that blocks me to continue on ''Dawnguard DLC'' I completed the quest named Bloodline.I refused the gift of Harkon and then I got banished from castle.After I get in the boat and hang around a little bit I went Fort Dawnguard but there wasn't any vampire attack and when I try to speak with Isran,I couldn't talk about anything but ''Training in Heavy Armor-Advices etc.''.As last hope I tried console commands that written in the ''UESP Wiki Page'' like ''setstage-setobjectivedisplayed-resetquest''.But it didn't work at all.It really tires me.(And BTW The UESP says the problem was getting into the boat).I searched for a solution so many hours but nothing worked at all.And I don't have a previous save.Please HELP ME :sad:
