Hi, just wanted to tell you I have a similar problem (almost exactly the same) as jtharpla. The NetScript crash logs pointing to the same .nif file, and the crash being solved by doing the same file replacement. I attempted to do a fresh install first, and that still led to a crash. However, like jtharpla, I use a mod that modifies markarth (The People of Skyrim 2). I used Dyndolod ver 2.8, Skyrim 1.5.80, and Resource ver 2.7.
