Here is a photo of .png images that are stopping me from editing them and putting them into the game.

What it is is this:
I cannot alter the jockey silks in the game because of the 1.png to 6.png, I have tried in vain to delete these but then the game won't load...this is the same for changing ther horse colours in the game. I am on the latest patch and am stuck, is there anything I can?
