Erm. 1. You need to download the xml file, google it and its easy to download.
2. put your png images into the graphic folder but name it (like your team)
3. when acquired the xml. click it. then choose, i.e, player faces either small or normal, club logo> small or normall, once you click those, 4. on above, were there's a browse button, paste the folder location and then click proccess.
once all that done, then just reload the skin on the game and you should see it all.
Good luck and sorry for taking long i had'nt been playing it for a bit.
Also if none of that works, try seeing it from youtube, its hard to find it but there's a help on youtube
Good luck mate
