Whats the propper way to remove a mod? My game is telling me some files can not be loaded. I am afraid to go on, I dont want to crash my game!

I think that's more of an advisory than anything else.

if you want it to go away, try:

Loading your game.

Saving your game into a new slot.

Loading your new save game.

Error messages should be gone.. and life goes on.. and hopefully game is just fine for you.

Thank you so much I am going to give it a try now.

It just means that you don't have a mod that you had activated on your last save.
