This is my first post, also there is a repeatable crash at the back exit of the Old Border Watch.

Hi, welcome to our forums.
Does it the CTD still occur with the newest patch and launcher?
If yes upload me one of your savegames from the Old Border Watch.
Savegames can be found here: documents\mygames\skyrim\saves
A savegame consists of two files: one .skse and one .ess (please zip them)
Thanks.

I had the same issue with Old Borderwatch. I was able to enter the building from the lower enterence once. When I left and tried to re-enter CTD. I did a fresh install of enderal and skyrim. Did not the fix the issue. This was after the most recent update.

How about following my suggestion from the post above?
Could you upload a savegame? I want to look into this problem.
