Error Message

If someone could tell me what I'm doing wrong, I'd really appreciate it.  I'm trying to make a "bandaged face" facepaint that would work for Zack from Angels of Death, because I couldn't find one.  I was following this (https://www.youtube.com/watch?v=Ode2RAQIx80) tutorial, although I had to follow the instructions for using .png files instead of .dds ones because Photoshop wouldn't let me open a .dds one.  I'm trying to import the .png file I made but can't seem to get it to work.
