A pink texture means Blender can’t find the image that is needed.
If you are linking it into your animation file – do NOT try to edit any materials or rigs etc inside the ANIM file.
You will need to make sure everything is ok with the original file (the one that is linking in)
So open it up and check that Blender can find where the texture image is. I can’t remember if it is actually stored in that blend file (makes huge files so I don’t usually do that) or if it is stored in a folder that inside the same directory ( called “textures”)
If you have moved things around it is easy to forget to bring the texture file.
It should be in “cgc-body-mechanics>lib>chars>cgc-box_rig>textures”
