Issues with importing content through file browser

Hello guys,I am having some issues with UE4.
I am following the twin stick shooter tutorial and downloaded the associated assets.
I am dragging the the folders into the project folders just like the video shows Here

The files are imported but when i drag for example a material it just loses the textures or when a drag an animation it just turns black like this:

Can anyone help me with this?

Thank anyways.

Try this.
Drop the folders sub folder of the TwinStick folder into the content root folder, afterwards from within the editor you can move the folder to a subfolder.

If the Twinstick folder is indeed the main folder, you likely have to fix references, meaning to assign the skeleton to the animations (right click the animations and chose assign skeleton). At least thats my conclusion from your video footage.
