the image you posted is just the edit data file (shows as 4 files on the pc whereas it only one on the ps3). im not sure how far youve got...
got all kits on your ps3?
have you downloaded the right file? (the one on the first page)
i have downloaded the link provided by the creater a few posts back. i have got as far as downloading it and extracting it to my desktop mate.
EDIT: I have no kits for Championship clubs or anything on my ps3, only Premier League kits and logo's, also I trying to download the link on the first page but the link says that the file is no longer available :S
