Ok first off, there is no need to post a poll at the top on this kind of subject.
It's kinda unessesary.
And like Lord said above, in order for your items to be seen in game, you need to put the coding that came with the item packet. The coding is located in Feral Heart> and it's a cfg file.
It should say Item cfg, and it can be turned into a notebook so you can add more coding.
Once you open that up, go ahead and open the coding in your item pack and paste them in the Feral Heart item cfg file and from there just save. Once you did this, your items should now be viewable.
Next you must out your texture in the the media>texture file so that way you actually "see" something instead of a default blocky white.
I see that you are having a common problem with downloading items.. here is a video that will show you just how to download the items right.
Now since you have placed all the textures into the right place I would skip to 3:25 in the video video for the next step you need to take in order to get the items. This video is just showing how to do exactly what Lord and Feareh said to do.
