The green crosshairs was a result of a change in the lua coding from the legion prepatch. This was fixed about a year ago. Think it was settexture to setcolortexture.
Just had a guild mate test it and it's working. I'd make sure you're on the newest version or the one directly previous if you don't like the new colors.
If your version is from anything pre 7.0 it will produce the flourescent green crosshairs and nothing else.
Hope that helps and appreciate the feedback and using my addon. Best of luck.
