I finally got around to playing Dawnguard yesterday and everything up until the quest "Chasing Echoes" has gone fine. I haven't experienced any lags or CTD's (well one, but I fixed that by deleting some script files from mods).

However, I've run into a bit of a problem. Without giving away spoilers, I was able to progress through "Chasing Echoes" fine until I needed to enter the Volkihar Ruins. Whenever I go through the door the game switches to the load screen (no rotating object) and then immediately crashes. I've even tried the movetoqt command with the proper quest ID and it still crashes during the loading screen. I've tried unchecking all my mods (not fully deactiving them from NMM, but unchecking all of them) and the crash would still occur. I reinstalled Dawnguard and I don't have any mod scripts running that would cause a problem (there's only one now and I tried deleting it, but it didn't fix anything).

Does anyone have any advice or have this happen to them? I really would like to finish this questline :-/

Just got a crash log. This is the last line in it before my game CTD's (tested twice, same exact like in each file).



Any ideas?
