Most definitely are not at all out-dated.
I successfully managed to get my items and markings working with no such problems.
However, if copying the items/markings over from your previous folders, then try reinstalling them into the game completely.
Meaning, opening the download .zip/.rar file and putting all of the markings into C: > FeralHeart > media > textures > markings and the items to the allocated folders. Replacing the .cfg files, too.
All that jazz.
