There are a few ways on how to download items, that I know of. I've had the problem where the items would not show up on my character as well. So, here's what you do:
MAC:
Download the items, copy ALL the items and paste them into the Items folder in the FeralHeart -> Media -> Items folder. Then you drag the items.cfg into the FHRoot.
WINDOWS:
Download the items and copy them ALL the items and paste them into the Items folder (again, still FeralHeart -> media -> Items). Now, drag the items.cfg into the MEDIA folder. (FeralHeart -> media). This worked for me, it should be the same for Dell and Toshiba.
