I been creating a cell

Been working fine until about an hour ago

I closed the CK

Came back later and when I try and open the esp it seems to keep trying but never completes the loading

If I start the game and do a coc to the cell the cell runs fine

What might be the issue and how can I fix it

Thanks

Depending on your machine it can take a while to load your plugin and Skyrim.esm, and the CK may appear to freeze during this time.

Have you tried just leaving it running for 5-10 minutes? Also make sure to click 'yes to all' to any errors or warnings that pop up during the load, as when those show up they halt the load process until handled.
