  Can someone help me before I lose my F#$%$#G Mind. I'm trying to put a character texture into project m 3.6, I got the texture to show up in the thing but when I try to drag the images over nothing happens, I tried It with multiple things but nothing. Can someone help me and or tell me what I am doing wrong before I lose it. This is to much stress to be dealing with on the weekend.
