Just as a reference to what I'm talking about, please refer to this thread:
As I stated in there, I was able to get my boot animation to work, but wanted to change the colors. I had opened each of the .png files in Photoshop, which opened in "Indexed Color." I changed each one to RGB color, desaturated, selective color, changed back to Indexed Color, and saved with the same file name. Now the boot animation doesn't work. Does anyone have any suggestions?
