This was the first thing I tried yesterday and after sitting in front of Preston for ten literal minutes, i concluded the conversation would not continue and there was something wrong. ETA: you know what, I'm going to stop question why this game be like this, because I just fixed this in the most ridiculous way, which was using the commands in kinggath's preston fix bat file but entering them manually instead of using the bat. I tried to use the bat file you linked and it didn't work when I had the problem as I am having the same issue. What were the commands that you used to manually fix it? I have tried all of the basic "complete quest" and "setstage" commands only for them not to work.
