If you look in your Drums UI folder you will see a folder called alternatives - inside this folder you will find the black and gold zipped folder. Unzip this folder and open the black and gold folder inside of it. You will find 6 files,copy and paste these in the images folder. You will have to confirm the over write permissions.
Note: Make sure you are completely logged out of game before making any changes to the UI
Hope this helps
