I've done something in the CK and have no idea if it's harmed my game. I was making an .esp for a preset when r/l interrupted (kids/puppy/mayhem) when I got back to the computer I thought I was at the step where you save, so I saved to create the .esp. Problem is I had already saved and what happened next is that I found ALL .esp icons in my game now looked like CK icons. My game still plays but I have no idea what this all means. Can I leave it like that, should I fix it, how do I fix it? Thanks, for any help you can give.

That just means that the .esp file type is associated with the creation kit (i.e. the creation kit is the default program to open them and if you double click on one it'll try to open it with the creation kit). It shouldn't be a problem.

Whew! Thank. you. so. much! I thought I would have to reinstall but I'm glad now that decided to post for help. I appreciate you helping.

I just thought of something else, if I release a mod will the .esp appear with the CK icon in the download for other players? How will this effect other players games--I want my mods to be safe. Thanks, again.
