Any help appricieted.

 

Random guess: Remove all the mods from your dlc folder, I can't run the editor with some mods I use.

 

same here. it's less fun playing without mods. but neccesairy for the editor

 

You can still play with mods, just not in the editor

 

fair enough. I don't feel like checking every time I boot TSW if I have mods on or off though.
