Ok So I just started playing dawnguard today on PC, Everything seemed fine with the dlc no glitches or problems at all, Until I get to Castle Volkihar (taking serana home for the quest) So I run up to the gate it doesn't open, Thought there was a problem, ran back to the shore, made sure serana followed me, talked to her on the bridge, gate opened, Then BAM! slap in the face! door into the castle won't open, No matter what, it's not locked, I click nothing happens, waited days, reloaded old saves, did the quest over and over again with new and old characters, happens again and again, so I decided to do some research, A few other's are having the same problem, But they tried thing's I didn't want to do, Re installing dawnguard, re installing all of skyrim, deleting everything just to get a fresh start, Still the door won't open for them, So I don't wanna try that, and from a couple of them that actually talked to Bethesda support about it, They basically said Bethesda told them to go F themselves and they can't and won't do anything about it, So.......Any ideas? Becuase this is complete [censored], And yes I and many others tried it with no mods. No ideas? well if you have the same problem start complaining so Bethesda will actually listen and fix it.
