Essential Tress Pack, what am i doing wrong?

Its odd… I put the folder in my project folder and i am able to load the meshes but as soon as i click to drag a tree over to my viewport, the whole tree goes grey with no materials. the Kite Demo works fine. its just the downloaded files from here. any clue?

thats the file. Could it be that the package is for a older UE4? I am under 4.17

And if thats the case… (outdated package) can you guys point towards a package that will work with 4.17 and above? seems like almost all of them here wont work with texture out the box.
