best I can say for most those errors is go in to the games files and try to locate the image and change it's file name to match the one the game says it cant find.
In your case you need to remove the space from the file so it reads as '$cowgirlyellow bust3.png' the game files has it as '$cowgirl yellow bust3.png'
and if you run in to any '%20" in the file that causes error replace them with a space
