Bug/Issue How do i fix this?

I am getting this error that i have no idea what it is about, im farely new to modding and i didnt know where to post this so, here it is.
I had a problem whit this "item error" in pierre's store which i fixed, and then i went to carpenter and could not
buy wood and stone, those 2 were unclickable, but it was still there.
Also CJB's item spawner would close it self on its own when i would hower above certain "box" and would act like the carpenter thing i mentioned above.

I also included the Error log in attached files.

Help would be aprittiated.

 

You can fix that by resetting your content files.

It looks like you installed an outdated XNB mod (the ones that replace files in your game's Content folder). I suggest avoiding those, since they can cause problems like that.

 

The error is gone! Thanks a ton!
Gonna watch out for those outdated xnb files in the future.
