When I open creation kit and load Skyrim.esm and my esp and set it as active it loads and I click Yes to All. And it stops working and I have to click close. It happens for being active and not being active for only that esp file, other esp files and Skyrim.esm by itself load fine. I've spent a lot of time on this esp and don't want to have to start all over. Any help on this?

EDIT: I have tried reinstalling the Creation kit, I can visit the cell fine in the game by using the 'coc cellnamehere' command. Creation Kit just doesn't want to open it. So nothing is corrupt.

Is there anything I can do?

Was your mod dependent on any others? Only thing I can think of is what happened to me with the GECK a while back when I tried to edit a plugin that needed a master file that I had removed.

What happened was I turned Creation Kit off when I was bored, and like 45 seconds later I turned it back on and it started happening. I've reinstalled, same problem.

I can visit it in Skyrim. And it works fine in Skyrim. Creation Kit doesn't like it though.
